LM358NG - Dual 1MHz Op Amp | onsemi | Signal Conditioning

onsemi LM358NG is a dual general-purpose operational amplifier with a 3 V to 32 V supply range, 1 MHz gain-bandwidth product, and 0.6 V/µs slew rate in an 8-pin PDIP package. The device provides two amplifier channels in one IC, uses a common-emitter output stage with capacitive load capability, and is designed for operation from either a single supply or split supplies. Its low-power architecture and input bias current of 100 nA make it suitable for battery-powered, industrial-control, sensor-conditioning, and general analog signal-processing circuits. An operational amplifier is an amplifier IC whose open-loop gain and feedback network determine the gain of a closed-loop circuit. The dual amplifier belongs to the hierarchy of analog amplifiers, signal-chain ICs, and semiconductors. Unlike a precision rail-to-rail amplifier, the LM358NG is primarily intended for conventional supply-voltage operation and can accept input common-mode voltages extending toward ground or the negative supply, VEE. This makes it useful in single-supply systems where signals remain near the lower supply rail. Key features include two amplifier sections, a 3 V to 32 V operating supply range, 1 MHz gain-bandwidth product, 0.6 V/µs slew rate, 100 nA input bias current, and 7 mV input offset voltage. The dual configuration reduces package count and board area when two independent analog functions are required. Commercial temperature operation is identified by the distributor listings, while the low-power drain supports battery-operated instrumentation where every milliampere affects useful runtime. The internal architecture provides useful behavior for low-frequency, cost-sensitive analog designs. Its approximately 1 MHz bandwidth permits operation well below audio frequencies and supports common feedback networks for amplification, filtering, comparison, and summing functions. The 0.6 V/µs slew rate is adequate for signals whose required full-scale transition time is not extremely short. As with any non-rail-to-rail amplifier, designers should verify input and output operating ranges against the actual supply voltages and signal amplitudes. Typical uses include low-side current sensing, sensor amplification, transducers, audio preamplifier stages, active filters, and general instrumentation. In a 5 V system, the dual structure can process two channels or use one section for filtering and the other for amplification. In split-supply circuitry, the common-mode input range extending toward ground or VEE supports bipolar-style signal conditioning without requiring a separate rail-to-rail input device. The primary design consideration is power-rail compatibility. The LM358NG supports 3 V to 32 V operation, but output swing and common-mode limits remain constrained by the supplies. PCB layout should keep input traces short, provide a solid ground plane, and place power-bypass capacitors close to the supply pins. Stable feedback components and adequate output isolation are also important when driving capacitive loads. This product page consolidates verified onsemi and distributor information, pricing context, package details, pin assignment, alternative-device guidance, and practical application notes. It is intended to help engineers evaluate whether the DIP-8 dual amplifier fits a new design or a repair before comparing it with other pin-compatible devices.

LM358P

LM358P - Dual 700kHz Operational Amplifier | Texas Instruments

The Texas Instruments LM358P is a dual operational amplifier packaged in an 8-pin PDIP. Each of its two independent channels provides high voltage gain, internal frequency compensation, and operation from a single supply, with a verified operating range of 3 V to 32 V. The LM358 family is specified at 700 kHz gain-bandwidth product and 0.3 V/µs slew rate, making it a general-purpose choice for signal conditioning and amplifier stages that operate from a wide supply-voltage range. An operational amplifier, or op amp, is a voltage-controlled differential amplifier whose open-loop gain is intended to be shaped by external feedback. The LM358P contains two separate amplifier channels in one 8-pin package, reducing board area compared with two discrete single-channel devices. Internally frequency-compensated channels simplify closed-loop design by reducing the additional compensation work normally required for stable operation. Key features include two independent amplifier circuits, high gain, internal frequency compensation, single-supply operation, and a wide 3 V to 32 V supply range. The 700 kHz bandwidth supports general-purpose signal conditioning rather than high-speed precision work, while the 0.3 V/µs slew rate limits how quickly a large output transition can occur. These characteristics make the device suitable for conventional industrial and consumer analog signal paths operating from a single supply. The LM358P is offered in a through-hole PDIP package, which supports manual assembly, prototyping, educational designs, and repair work. The dual-channel configuration allows a board to implement two amplifier functions without using two separate packages. Because the verified data identifies the device as a standard general-purpose amplifier rather than a rail-to-rail precision op amp, applications requiring rail-to-rail input or output operation, low offset, or low noise should verify those requirements against the manufacturer datasheet before final design approval. Typical uses include single-supply buffer stages, sensor-signal conditioning, feedback amplifiers, integrators, comparators, and general analog control blocks. Two channels can also implement related functions such as an instrumentation-style buffer or a transimpedance amplifier, provided the designer accounts for the LM358P's input common-mode range, output swing, output-current capability, stability requirements, and noise characteristics. A key design consideration is power bypassing. Place the supply-decoupling capacitor close to the positive supply and ground pins, and keep feedback components and signal routing compact to minimize oscillation and pickup. Component selection should preserve useful loop gain and phase margin rather than relying only on nominal bandwidth. For applications with unusually high precision, very low noise, or demands for rail-to-rail operation, verify the complete electrical limits before committing to this device. This page consolidates the verified distributor and manufacturer information for LM358P, adds a pin-level package reference, compares documented drop-in candidates, and organizes practical sourcing and design guidance for engineers evaluating the Texas Instruments LM358P.

LM358PE3

LM358PE3 - Dual 700 kHz Op Amp in 8-PDIP | Texas Instruments

Texas Instruments LM358PE3 is a dual, general-purpose operational amplifier with a 3 V to 32 V supply range, 700 kHz gain-bandwidth product and 0.3 V/µs slew rate, housed in an 8-pin PDIP package. The device contains two independent, high-gain, internally frequency-compensated amplifiers capable of operating from a single supply or dual supplies. An operational amplifier is a high-gain differential-input semiconductor that compares two voltages and drives its output to amplify the difference between them. In the broader hierarchy, the LM358 is a dual operational amplifier, a general-purpose analog amplifier within the amplifier-IC and semiconductor categories. Its two independent channels can implement noninverting, inverting, summing, comparator, and feedback-control functions. The principal characteristics of the LM358PE3 are its 700 kHz gain-bandwidth product, 0.3 V/µs slew rate, low supply-current draw, high voltage capability and single-supply operation. The manufacturer describes the LM358 family as suitable for general-purpose signal conditioning when the circuit does not require rail-to-rail input or output swing. Its broad supply-voltage range permits use in 3 V, 5 V, 12 V and higher-rail systems when the individual channel remains within its operating limits. Each amplifier includes high gain and frequency compensation, allowing closed-loop operation without external compensation in many standard gain configurations. The 0.7 MHz bandwidth supports low-frequency signal paths more effectively than high-speed precision amplifiers, while the 0.3 V/µs slew rate limits large-signal response. Input offset voltage, input bias current, output-current capability and common-mode limits must be checked against the manufacturer datasheet for the chosen operating conditions. Typical applications include bridge and resistive sensor amplification, audio preamplification, low-frequency active filters, motor and actuator control loops, battery-powered monitoring, and general industrial signal conditioning. Two independent channels can process separate sensor signals or form the two halves of an instrumentation circuit, although common-mode and output-swing restrictions still apply. For reliable PCB implementation, preserve the manufacturer's recommended bypass capacitance, provide a low-impedance ground return, and keep feedback components close to the relevant amplifier pins. A socketed PDIP design is convenient for prototyping and repair, although a soldered package provides better mechanical reliability in production. This product page combines the LM358PE3's principal electrical characteristics with pin-level implementation guidance, application fit, drop-in alternatives and a side-by-side engineering comparison. These practical details help designers move from general amplifier selection to a reviewable circuit design.

LM358PE4 - Dual 700 kHz Op Amp, 8-PDIP | Texas Instruments
LM358PE4

LM358PE4 - Dual 700 kHz Op Amp, 8-PDIP | Texas Instruments

Texas Instruments LM358PE4 is a dual general-purpose operational amplifier with a gain-bandwidth product of 700 kHz, a slew rate of 0.3 V/µs, and a supply range extending to ±16 V per rail, housed in an 8-pin PDIP package. The device contains two independent amplifiers, making it suitable for dual-channel signal conditioning, filtering, comparisons, and basic feedback-control circuits. An operational amplifier is a voltage-feedback analog IC that uses differential input voltage to produce an amplified output voltage. Operational amplifiers belong to the amplifier hierarchy, support precise closed-loop operation when paired with external resistors, and are widely used in industrial controls, sensor interfaces, audio electronics, and power-management systems. The LM358PE4 belongs to the industry-standard LM358 family and combines two amplifiers in one package. Key electrical characteristics include a typical input offset voltage of 300 µV, a low 0.7 mA supply-current drain that is independent of supply voltage, and a common-mode input voltage range that includes ground. These features suit battery-powered, sensor-driven, and single-supply circuits where low cost, ground-referenced inputs, and two amplifiers in one package are important. The device also supports high differential input voltage capability for cost-sensitive applications. The LM358PE4 uses a bipolar voltage-feedback architecture and is specified for general-purpose analog signal processing. Its 700 kHz gain-bandwidth product makes it suitable for low-frequency audio, control, and instrumentation tasks rather than high-speed precision applications. With a 0.3 V/µs slew rate, it can produce larger output transitions more slowly than modern rail-to-rail CMOS amplifiers, so designers should check bandwidth, output swing, and stability requirements before increasing closed-loop gain. Typical applications include two-channel sensor conditioning, low-frequency active filters, audio preamplification, comparators, and industrial control interfaces. In each case, the two amplifiers can process independent signals or form a cascaded signal chain. Stable operation also requires suitable bypassing, careful grounding, and output-load consideration because the LM358PE4 is not a rail-to-rail-input or rail-to-rail-output device. For single-supply designs, bias the non-inverting input above ground and use decoupling close to the supply pins. Check the common-mode and output-voltage limits against the actual signal range, and avoid relying on output saturation as a precise comparator function. Prototype the gain, slew rate, and capacitive-load behavior before committing a high-volume design. This page combines the manufacturer specifications, package and pin information, supported alternatives, application guidance, and design notes needed to evaluate the LM358PE4. It also organizes replacement and selection questions around the verified 8-PDIP footprint, 700 kHz bandwidth, 0.3 V/µs slew rate, and 36 V maximum total supply capability.

LM358PT

LM358PT - Dual 3-32V Op Amp, 1.1MHz | STMicroelectronics

The STMicroelectronics LM358PT is a dual general-purpose operational amplifier containing two independent, internally frequency-compensated amplifiers. Its 3 V to 32 V single-supply operating range, 1.1 MHz unity-gain bandwidth, 100 dB DC voltage gain, and low input common-mode voltage of 0.6 V make it suitable for general signal conditioning. The device is supplied in an 8-pin TSSOP surface-mount package. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its inverting and non-inverting inputs. The LM358 belongs to the dual-operational-amplifier category within the broader amplifier IC and analog semiconductor hierarchy. Its two independent channels can amplify AC or DC signals, buffer inputs, perform comparisons, and support feedback-based circuit functions. Internal frequency compensation simplifies stable operation without an external compensation network. The principal features of the LM358PT include two amplifier channels in one package, a wide 3 V to 32 V supply range, 1.1 MHz unity-gain bandwidth, and 100 dB large-signal DC voltage gain. Internally compensated operation supports practical use without external compensation capacitors. The 8-pin TSSOP package also provides a compact surface-mount option for industrial control, instrumentation, sensor interfaces, and consumer equipment where board area matters. Technically, the LM358PT is designed for single-supply operation while accepting input signals close to the lower supply rail. The verified 0.6 V input common-mode figure gives designers a concrete limit when working from a 3 V or 5 V rail. Its bandwidth is sufficient for many audio, control, and instrumentation signals, but it is not a high-speed precision op amp. Applications requiring very low offset, very low noise, rail-to-rail output, fast slew rate, or high DC accuracy should be reviewed against the device limits before production release. Typical uses include sensor-signal conditioning, active filtering, transducers, relay and solenoid drivers, audio and communications interfaces, and general control loops. The two channels can process related signals in a compact circuit or implement separate functions. Because output-current capability and slew-rate limits remain important in real designs, the load should be checked against the manufacturer's operating information rather than assumed from the wide supply range. A key design consideration is input common-mode range: the LM358PT can operate from 0.6 V above the negative supply, but it does not provide true rail-to-rail input or output swing. Designers should also account for the effects of supply bypassing, output loading, stability with capacitive loads, and the power dissipation created by the voltage difference across each amplifier. This product record combines manufacturer and distributor information with a practical selection guide, package-aware alternatives, comparison parameters, and implementation notes. It is intended to help engineers confirm footprint, electrical fit, sourcing status, and application suitability before selecting LM358PT for a PCB redesign or new design.

Designed for low-power consumption and high open-loop gain, it is suitable for signal conditioning, feedback control, and analog signal amplification across industrial, consumer, and instrumentation systems. Each amplifier can operate from a single supply or from split positive and negative supplies. An operational amplifier is an analog semiconductor that uses high-gain differential feedback to amplify the difference between two input voltages. The LM358 belongs to the dual operational-amplifier, voltage-feedback, analog IC, and power-management signal-chain hierarchies. Its two channels share common supply pins but otherwise provide independent amplifier functions, allowing one package to implement two signal-processing paths. The principal advantages of the LM358PW are its dual-channel integration, low-power operation, high gain, broad supply-voltage range, and established industry-standard pin arrangement. The TSSOP-8 footprint saves board area compared with larger dual-op-amp packages, while two channels reduce the component count in designs that require duplicated gain or buffering stages. These characteristics make the device a practical baseline for general-purpose analog designs. Its architecture is suited to voltage-feedback applications in which the amplifier operates with external negative feedback. The package provides separate inputs and outputs for both channels, while the power terminals are shared. Designers should account for input common-mode limits, output swing, bias current, noise, slew rate, stability, and load capability when setting the operating point; consult the manufacturer datasheet for exact limits and test conditions before finalizing a circuit. Typical applications include DC signal conditioning in sensor interfaces, closed-loop control for industrial equipment, audio preamplification, analog sensor amplification, and general buffer stages. The two-amplifier configuration is especially useful when a board needs one channel for signal amplification and another for filtering, level shifting, active feedback, or output buffering. The primary design consideration is circuit stability. Feedback-network values, source and load impedances, output loading, and supply bypass capacitance affect closed-loop performance. Place the required decoupling capacitor close to the supply pins, use short feedback paths, and verify common-mode and output-swing margins across the intended input range. Add input or output protection when external wiring can introduce transients beyond the device ratings. This product page combines the manufacturer product description, distributor package and catalog information, documented cross-reference candidates, and practical application guidance. It also highlights the distinction between electrically similar devices and true TSSOP-8 drop-in options, helping engineers evaluate footprint compatibility, temperature behavior, supply range, and channel-level performance before redesigning an existing PCB.

LM358PWG4

LM358PWG4 - Dual 700kHz Op Amp, 16V, TSSOP-8 | Texas Instruments

The Texas Instruments LM358PWG4 is a dual general-purpose operational amplifier with two independent amplifiers, 700 kHz gain-bandwidth product, and 0.3 V/us slew rate. Designed for single or dual supply operation, it accepts a 3 V to 32 V total supply range and is packaged in an 8-pin TSSOP. The LM358PWG4 is supplied in tube packaging for a 0°C to 70°C commercial operating-temperature grade. An operational amplifier is an analog signal-processing IC that compares its inverting and non-inverting inputs and amplifies the voltage difference between them. Within the broader semiconductor hierarchy, an op amp is an amplifier IC and part of the analog signal-conditioning family. The dual configuration in the LM358PWG4 places two general-purpose amplifiers in one package, reducing component count and board area in designs that need two similar signal-processing channels. The key operating characteristics are a 700 kHz gain-bandwidth product, 0.3 V/us slew rate, and operation from 3 V to 32 V. The documented output-swing range extends from approximately ±1.5 V to ±16 V depending on supply conditions and load. Its general-purpose architecture makes it suitable for conventional amplifier, comparator, summing, and feedback applications where moderate bandwidth and broad supply compatibility are more important than rail-to-rail input or output operation. The LM358 family is particularly useful when two independent channels can share a common supply. Because both amplifiers are in the same package, board designers can shorten supply routing and maintain symmetrical placement of the two channels. The 8-pin TSSOP package also supports compact PCB construction, although its narrow lead pitch requires careful assembly and adequate solder-joint inspection. Typical uses include audio preamplification, sensor-signal conditioning, low-frequency active filters, comparators with pull-up resistors, and general instrumentation. In these applications, the 700 kHz bandwidth handles low- and mid-frequency signals, while the 0.3 V/us slew rate helps control distortion for moderate-amplitude signals. The broad 3 V to 32 V supply range also supports both low-voltage portable systems and higher-voltage industrial control systems. Designers should evaluate output swing, input common-mode range, bias current, offset voltage, noise, and stability for the exact operating conditions before assigning gain or filter coefficients. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs should be biased so they remain in a defined common-mode state. The two channels are independent, but sharing a package does not guarantee matched behavior. This product page combines the verified LM358PWG4 electrical and packaging characteristics with application guidance, replacement considerations, and practical selection criteria. It helps engineers identify where the dual 700 kHz amplifier, 3 V to 32 V supply capability, and compact TSSOP-8 package provide useful design advantages without overlooking rail-range or precision requirements.

LM358PWRG3

LM358PWRG3 - Dual 16V 700kHz Op Amp | Texas Instruments

Texas Instruments LM358PWRG3 is a standard general-purpose dual operational amplifier with two amplifier circuits, a 700 kHz gain-bandwidth product, and a 16 V maximum supply rating. It is packaged in an 8-TSSOP for surface-mount assembly. The LM358 family is a widely used general-purpose op-amp platform for low-frequency analog signal conditioning, sensor interfaces, and basic amplifier configurations. An operational amplifier is a high-gain, differential-input analog IC used to amplify voltage differences. In its broader hierarchy, an operational amplifier belongs to the amplifier-IC and analog-signal-chain categories. A dual op amp integrates two amplifier channels into one package, allowing a design to use both channels for related tasks such as signal conditioning, buffering, filtering, or feedback control. The LM358PWRG3 combines that two-channel architecture with a compact TSSOP-8 footprint. The identified part is a standard, general-purpose device rather than a rail-to-rail precision amplifier. Its stated 700 kHz gain-bandwidth product supports applications where the closed-loop bandwidth is substantially lower after accounting for the selected noise gain. The 16 V maximum supply rating places the device in the single-supply operating class shown by the product listing. Tape-and-reel packaging supports automated pick-and-place and high-density PCB assembly. The dual-channel organization can reduce component count when a board needs two related amplifier functions. One channel might condition a sensor output while the other provides buffering or active feedback, although the final circuit must satisfy the device's input, output, common-mode, stability, and load requirements described in the manufacturer datasheet. The 8-TSSOP package offers a smaller board area than an SOIC-8 package, but its lead pitch requires careful component placement and assembly planning. Typical application areas include transducer signal conditioning, low-frequency closed-loop control, analog sensor interfaces, active filters, and general buffer or gain stages. In a sensor interface, the op amp may amplify a small differential signal before downstream conversion. In a filter, its gain and bandwidth behavior participate in setting the transfer function. In a feedback-control circuit, the dual package can support related signal paths without requiring two separate single-channel packages. Designers should follow the manufacturer datasheet for the complete electrical limits, pin assignments, common-mode range, output-swing limits, input-bias-current behavior, noise characteristics, and recommended operating conditions. Decoupling and layout decisions should be based on the intended circuit topology, especially when the amplifier drives capacitive loads or operates close to supply rails. PCB signal-return paths should remain short and preserve a low-impedance ground connection. This page combines the exact package and headline device information with practical selection guidance, verified source links, an explicit data-completeness assessment, and engineering-focused application notes. It also distinguishes pin-compatible alternatives from broader functional equivalents so engineers can make a replacement decision without assuming that similar amplifier performance guarantees footprint, bias, stability, or operating-range compatibility.

LM358PWRG4 - Dual 700 kHz Op Amp, 30 V, TSSOP-8 | TI

Texas Instruments LM358PWRG4 is a dual general-purpose operational amplifier with two independent amplifiers, 30 V maximum supply capability, 700 kHz gain-bandwidth product, and an 8-pin TSSOP package. The LM358PWRG4 is designed for cost-sensitive applications requiring one amplifier that can operate from a single supply, accept input signals near ground, and provide reasonably wide common-mode input range. Both channels share the same supply pins and are not intended for direct parallel operation. An operational amplifier is a high-gain differential amplifier used to compare, amplify, filter, buffer, or scale signals. The LM358 belongs to the operational-amplifier hierarchy within analog signal-chain ICs and broader semiconductor devices. Its internal frequency compensation removes the need for an external compensation capacitor in most closed-loop configurations, simplifying PCB layout and reducing the component count in cost-sensitive industrial, consumer, instrumentation, and control designs. The principal features of the LM358PWRG4 include a dual-amplifier configuration, 700 kHz gain-bandwidth product, 0.3 V/us slew rate, 3 V typical low supply-current drain, approximately 3 mV typical input offset voltage, and approximately 2 nA typical input offset current. Its common-mode input range can include ground, making it useful in single-supply sensor interfaces where the signal begins near 0 V. The 30 V maximum supply rating provides additional operating margin compared with devices limited to lower supply voltages. Internally, the LM358 uses a bipolar transistor input and output stage optimized for economy and supply-voltage flexibility rather than rail-to-rail input or output operation. The amplifiers are frequency-compensated for stable operation with external feedback networks. Because output swing and input common-mode range are not rail-to-rail, a designer should check the signal amplitudes and output voltage required by the selected feedback network, especially with low supply voltages. Typical uses include low-cost sensor-signal conditioning, current-loop and grounded-transducer interfaces, audio preamplification, voltage comparators, active filters, motor and relay control, industrial equipment, and general-purpose analog modules. The TSSOP-8 footprint supports compact, high-density PCB layouts, while the dual channel can implement two matched amplifier functions or one differential amplifier followed by a separate amplifier stage. The main design consideration is supply headroom. Check input common-mode limits, differential input limits, output swing, load capability, and stable feedback gain for the actual supply voltage. Place bypass capacitors close to the supply pins and maintain a short, quiet output path, especially when the amplifier drives a long trace or an ADC input. Because the part is listed at last-time-buy status, production designs should evaluate an explicitly qualified second source rather than assume unlimited lifecycle availability. This page combines the exact LM358PWRG4 ordering information, technical characteristics, lifecycle status, package details, and engineering guidance into one purchasing reference. It also identifies same-footprint alternatives and explains where analog-performance qualification must be checked before substitution.

Each of the two amplifier channels offers a gain bandwidth product of approximately 1 MHz with rail-friendly output swing suited to single-supply operation, making it a workhorse signal-conditioning amplifier for 12V automotive and 5V industrial systems. An operational amplifier (op-amp) is a high-gain voltage amplifier with differential inputs and a single-ended output; within the component hierarchy it belongs to the amplifier IC family, under integrated circuits, and is a core building block of analog signal chains. Dual op-amps such as the LM358-Q1 integrate two independent channels in one package, halving board area versus two single amplifiers while sharing supply rails. Key features include two independent amplifier circuits, a 1 MHz class gain bandwidth, low input offset suitable for general-purpose sensing, operation from single or dual supplies, and AEC-Q100 automotive qualification with temperature grading that supports harsh under-hood environments. The wide supply range allows direct interfacing with battery-backed rails and regulated 5V logic domains. Architecturally, the LM358-Q1 family traces to the classic LM358 bipolar design updated for automotive quality systems, with TI manufacturing controls per its automotive flow; the related LMV358-Q1 variant adds rail-to-rail output for low-voltage rails per the LMV321-Q1/LMV358-Q1/LMV324-Q1 datasheet. Typical applications include automotive sensor signal conditioning, current-sense amplification front-ends, active filters, comparators and level shifters, and battery-management monitoring stages in vehicle ECUs and industrial controllers. Design tip: with a 1 MHz GBW, keep closed-loop gains modest (10x or below) to preserve bandwidth and phase margin; check the output swing versus load, since the classic LM358 output does not reach the positive rail.

LM358S-13 - Dual Low-Power Op Amp, 3-32V | Diodes Incorporated

Diodes Incorporated LM358S-13 is a dual, low-power operational amplifier containing two independent high-gain, internally frequency-compensated amplifiers. It operates from a single supply over a 3 V to 32 V range, provides a gain bandwidth of 100 dB as identified by Mouser, and is packaged in an 8-pin surface-mount SO package. The two amplifier channels can be used independently for signal conditioning, voltage comparison, feedback control, or general-purpose analog functions. An operational amplifier is an analog signal-processing IC that compares voltages applied to its inverting and non-inverting inputs and amplifies the difference between them. The LM358 family belongs to the dual operational amplifier category within the broader hierarchy of amplifiers, analog ICs, and semiconductor devices. Its internally compensated architecture simplifies closed-loop design because no external compensation components are required for ordinary voltage-feedback operation. The principal benefits of the LM358S-13 are its wide single-supply operating range, dual-channel integration, low-power designation, and internally frequency-compensated architecture. Two independent amplifiers in one package reduce component count and board area compared with two separate single operational amplifiers. Its 3 V minimum supply supports lower-voltage systems, while the 32 V maximum permits connection to conventional higher-voltage industrial rails when appropriate protection and signal limits are respected. The LM358 series was designed specifically for operation from a single power supply. In a single-supply circuit, the common or supply-return node is the reference for signal inputs, so input and output voltages must remain within the device's operating limits. Grounding inputs near the common node is important when processing small signals because the output cannot swing below the lower rail. The second amplifier can complement the first as an inverter, comparator, transimpedance amplifier, or buffer in the same package. Typical applications include low-voltage sensor interfaces, DC signal amplification, threshold detection, loop-error amplification, transducer buffering, and general dual-channel analog conditioning. The 8-pin SO package is suitable for compact surface-mount PCB assemblies, although exact connector and test-point placement should follow the manufacturer's pin configuration. Decoupling capacitors should be placed close to the supply pins, and sensitive analog traces should remain away from switching nodes and high-current return paths. Design trade-offs must be checked against the complete electrical characteristics before production use. In particular, input common-mode range, output swing, input bias current, input offset voltage, supply-current behavior, noise, and output-current capability determine whether a particular application is electrically suitable. This page combines the confirmed product identity and electrical headline values with package guidance, drop-in comparison information, application patterns, and practical layout recommendations for faster engineering evaluation.

The device operates from a single power supply over a wide voltage range and is also specified for operation at supply voltages up to ±16 V, corresponding to a total supply range of 32 V. An operational amplifier is an analog signal-conditioning IC that uses differential feedback to amplify the voltage difference between its inverting and non-inverting inputs. The LM358 belongs to the general-purpose operational-amplifier family, which sits within the broader amplifier IC and semiconductor hierarchy. Its two independent channels allow one package to provide separate amplification paths for sensors, control loops, audio stages, or general analog signal processing. The principal features of the LM358ST include two independent amplifier circuits, internally integrated frequency compensation, a common-mode input range that includes ground, and low-power operation from a single supply. The 800 kHz bandwidth supports general-purpose closed-loop signal paths without requiring an external compensation network. Its 8-pin TSSOP format provides a compact surface-mount option for mixed-signal boards with limited routing area. Each channel uses a differential input stage and an internally compensated voltage-feedback architecture. Because the channels are independent, one can amplify a sensor signal while the other performs filtering, comparison, level conversion, or feedback control. Common-mode operation near ground is particularly useful for circuits powered from a single positive rail, where input signals may remain close to 0 V. Designers should still verify input and output swing against the specific supply voltage used in the final circuit. Typical uses include low-side current sensing, sensor amplification, audio and communications interfaces, industrial control, and embedded instrumentation. In an STM32-based measurement system, the two channels can condition separate analog inputs before conversion by the microcontroller. The device can also implement active filters or comparators because its outputs can typically swing close to ground when operated from a positive single supply. For PCB design, place input resistors, feedback components, and bypass capacitors close to the relevant pins to reduce parasitic feedback and noise pickup. A local supply decoupling capacitor should be positioned near pin 8, with the ground return routed directly to pin 4. Check input common-mode voltage, output swing, stability with the intended feedback network, and channel thermal dissipation before committing the layout. This product page combines the exact LM358ST package and electrical identity with sourcing guidance, genuine drop-in options, pin assignments, and practical application notes. It is intended to help engineers compare footprint, function, supply range, bandwidth, and design constraints faster than a raw distributor listing while preserving manufacturer datasheet requirements for final qualification.

LM358TPX/NOPB

LM358TPX/NOPB - 2-Channel 1MHz 32V Op Amp | Texas Instruments

Texas Instruments LM358TPX/NOPB is a two-channel, general-purpose operational amplifier with a 1 MHz gain-bandwidth product, 32 V maximum supply capability, and an 8-DSBGA package. Each channel is a high-gain, internally frequency-compensated amplifier designed for single-supply operation, with typical performance figures including 65 dB common-mode rejection, 0.1 V/us slew rate, approximately 500 uA supply current per amplifier, and 2 mV input offset voltage. An operational amplifier is a high-gain analog building block used to amplify, buffer, compare, or sum signals. The dual-amplifier configuration provides two independent channels in one package, reducing board area when a circuit needs two general-purpose amplifier functions. Internally frequency compensation makes the devices straightforward to use for stable closed-loop gains without external compensation components, while the wide supply-voltage range supports both low-voltage and higher-voltage industrial designs. The 1 MHz gain-bandwidth product is suitable for audio, control, sensing, and signal-conditioning circuits that do not require high-speed operation. A 65 dB common-mode rejection ratio helps reject equal-mode interference, and the 0.1 V/us slew rate defines useful large-signal bandwidth for moderate-frequency waveforms. The 500 uA supply current per amplifier supports low-power signal paths, while the 32 V maximum rating provides additional headroom in applications using higher supply rails. The LM358 family architecture supports operation from a single positive supply or a split supply. Because each amplifier is independent, one channel can perform one function while the other performs a separate function. The 2 mV typical input offset voltage is suitable for many cost-sensitive general-purpose designs, although precision measurement systems should account for offset, bias current, noise, and temperature drift in their error budget. Typical uses include microphone preamplification, sensor signal conditioning, battery-powered monitoring, current-loop interfaces, comparator-style threshold detection, and general DC signal amplification. The 8-DSBGA format is useful where PCB area is constrained, but its small land pattern requires careful assembly and adequate thermal design. The tape-and-reel ordering option also supports automated production handling. For reliable layout, place input, output, and supply connections to minimize parasitic resistance and capacitance. Keep sensitive input traces short, provide local supply bypassing, and verify the exposed-ball thermal path against the PCB copper area. Designers should also account for input common-mode limits and output-current limits; the amplifier does not operate as a rail-to-rail input or output device. This product page organizes the key electrical characteristics, package information, sourcing terms, replacement constraints, and engineering guidance for the LM358TPX/NOPB. It also distinguishes same-footprint alternatives from broader LM358-family devices whose packages or electrical operating limits require a different design review.

LM359M - Dual 400 MHz Norton Amplifier | Texas Instruments
LM359M

LM359M - Dual 400 MHz Norton Amplifier | Texas Instruments

The Texas Instruments LM359M is a dual, high-speed, programmable current-mode Norton amplifier with two independent amplifier circuits, a 400 MHz gain-bandwidth product, and a 60 V/µs slew rate. The LM359M is supplied in a 14-SOIC package and is intended for applications requiring high-frequency operation, user-programmable gain, and flexible feedback arrangements. An operational amplifier is an active analog signal-conditioning device that amplifies the difference between two input voltages while using negative feedback to set closed-loop behavior. The LM359 uses a current-mode, or Norton, input architecture rather than the voltage-input architecture common in conventional voltage-feedback amplifiers. This topology can provide high speed and high gain-bandwidth performance when supported by suitable external current-setting and compensation networks. The LM359 family provides two amplifiers in one package, reducing component count in dual-channel signal paths. Its high gain-bandwidth product makes it useful in video, communications, instrumentation, and active-filter circuits where signal bandwidth matters. The user-programmable gain and frequency characteristics allow circuit designers to tailor amplifier behavior with external resistors and capacitors, although stability must be checked for each selected feedback network. The LM359M is a 14-SOIC device with two amplifier sections, separate supply pins, and exposed package leads for through-hole board assembly or compatible PCB land patterns. Because it is a current-mode amplifier, input bias current, feedback-current selection, compensation, and maximum output swing require attention during design. The 400 MHz gain-bandwidth product does not mean every closed-loop circuit will operate at 400 MHz; usable bandwidth depends on gain, noise, stability, loading, and the external network. Typical uses include wideband video signal conditioning, pulse shaping, communications interfaces, active filters, oscillators, and instrumentation. The device is also suitable for educational and laboratory designs where a programmable high-speed analog amplifier is useful. Designers should begin with the manufacturer LM359 datasheet and verify the recommended external components for the intended gain and frequency response. A key design consideration is that LM359M is not a universal replacement for every voltage-feedback operational amplifier. Feedback topology, input bias-current behavior, compensation, output drive, and supply requirements must be checked against the original circuit. Stable operation also requires careful PCB layout, short feedback paths, suitable bypassing, and controlled parasitic capacitance. This page combines verified manufacturer and distributor information, package and application context, practical design guidance, and clearly identified data gaps. It is intended to help engineers evaluate LM359M for high-speed dual-amplifier designs without confusing its current-mode architecture with conventional voltage-feedback amplifier families.

LM359M/NOPB - Dual 400MHz High-Speed Amplifier | TI

Texas Instruments LM359M/NOPB is a dual, high-speed, programmable current-mode Norton operational amplifier with a 400 MHz gain-bandwidth product, 60 V/µs slew rate, 8 µA input bias current, and 40 mA output current per channel, packaged in a 14-SOIC tube package. The part is designed for high-frequency signal-chain work where user-programmable operating characteristics and stable inverting operation are important. The LM359 is an operational amplifier, a voltage-feedback signal-conditioning building block that compares an input signal with a feedback network and produces an amplified output. Its current-mode architecture places emphasis on high-frequency performance rather than the conventional high-impedance voltage-mode input used by many general-purpose amplifiers. The LM359 family therefore belongs to the broader category of analog ICs, operational amplifiers, and high-speed active signal-conditioning devices. Key features include two amplifier circuits on one monolithic IC, a 400 MHz gain-bandwidth product, 60 V/µs slew rate, and programmable amplifier operating characteristics. Each channel is broadbanded for high-frequency use, and the manufacturer identifies stable operation for inverting closed-loop gains of 10 or greater. The verified source data also lists 8 µA input bias current and 40 mA output current per channel, making the device suitable for analog signal conditioning, pulse processing, communications, and general-purpose amplification. The LM359M/NOPB ordering suffix identifies a specific Texas Instruments package and delivery configuration. The verified distributor data identifies the device as a dual general-purpose amplifier in a 14-SOIC case, while the target MPN is supplied in tube packaging. The NOPB designation is retained exactly as requested; package, temperature, and qualification details not explicitly present in the supplied data are marked as needed rather than inferred. Typical applications include high-frequency analog signal conditioning, communications interfaces, waveform shaping, pulse amplification, active filtering, and industrial or consumer control systems. Designers should preserve the recommended feedback and gain configuration, provide adequate bypassing, and verify stability experimentally because the current-mode Norton architecture and its programmable characteristics are not interchangeable with ordinary voltage-mode amplifier layouts without validation. For a new design, first confirm the required gain, bandwidth, output loading, supply arrangement, and package footprint against the manufacturer datasheet. Keep high-speed feedback traces short, place compensation and bypass components close to the relevant pins, and compare measured gain, phase margin, output swing, and slew behavior in the final board environment. This page synthesizes the verified manufacturer and distributor information with practical design guidance rather than claiming an unpublished full electrical table. Because the supplied web results do not include complete verified pin assignments, electrical limits, compliance declarations, or a reliable set of pin-compatible substitutes, those fields remain explicitly identified as data-needed. The most defensible purchasing and replacement decision requires checking the current Texas Instruments datasheet and distributor cross-reference results before production release.

LM359MX - Dual 60V/us High-Speed Amplifier | Texas Instruments

The Texas Instruments LM359MX is a dual, high-speed, programmable current-mode Norton amplifier with a 60 V/us slew rate, supplied in a 14-SOIC package. Each channel provides independent input-offset balancing, gain programming, frequency compensation, and output saturation control. The verified listing identifies two general-purpose amplifier circuits in one package, making LM359MX suitable for analog signal conditioning, waveform shaping, and programmable-gain systems. A current-mode amplifier, commonly called a Norton amplifier, senses input current rather than directly measuring input voltage. LM359MX uses that architecture to achieve high bandwidth and fast slew performance while allowing gain and compensation to be programmed with external components. Each amplifier can therefore adapt its dynamic behavior to a particular signal bandwidth, gain, or output-drive requirement rather than operating only with fixed internal settings. The two independent channels support simultaneous analog processing or separate signal paths. Programmable operating characteristics are useful when one circuit must amplify small instrumentation signals and another must process faster pulses. The 60 V/us slew rate helps preserve large-signal waveform fidelity, while the dual configuration can reduce component count where two compatible amplifier functions are needed. Typical uses include pulse and transient amplifiers, analog summing stages, video or communications interface signal conditioning, laboratory interfaces, and wideband control loops. Because operating characteristics are programmable, the external network around each channel is as important as the nominal device specifications. Feedback components, compensation values, source impedance, and output loading must be selected together to maintain intended bandwidth and stability. For PCB layout, use a grounded return path near each amplifier, keep sensitive input and feedback traces short, and place compensation components close to their associated pins. The tape-and-reel ordering suffix MX identifies the verified LM359MX package configuration, while the functional LM359 family documentation describes the shared dual current-differencing architecture and programmable operating behavior. This page combines the verified manufacturer and distributor listing data with engineering guidance for the LM359MX. It also makes missing electrical limits and availability values explicit rather than inferring them, allowing designers to evaluate the device against the full LM359 datasheet and current authorized-distributor inventory before releasing a design.

Texas Instruments LM359MX/NOPB is a dual, high-speed, programmable current-mode Norton amplifier IC with 400 MHz gain-bandwidth product, 60 V/µs slew rate, and two amplifier circuits in a 14-pin SOIC (D) package. According to the manufacturer product page and the LM359 data sheet, the device operates from a 5 V to 22 V supply, supports an operating temperature range of 0 °C to 70 °C for this ordering variant, and is intended for high-frequency signal conditioning, video, communications, and pulse applications. The LM359 uses current-differencing input stages rather than conventional voltage-input op-amp inputs, allowing the user to program amplifier operating characteristics with external components. Each amplifier is broadbanded for high gain-bandwidth product and fast slew rate, while stable operation is emphasized for inverting closed-loop gains of 10 or more. The two independent channels make the part suitable for dual-ended signal paths, differential interfaces, gain blocks, and active filtering. LM359MX/NOPB is supplied in tape-and-reel packaging with the manufacturer suffix MX. The component is a general-purpose precision analog building block rather than a digital or power-management device. Its 14-pin SOIC package supports conventional surface-mount assembly, but high-frequency layouts should minimize parasitic capacitance, provide adequate ground-plane continuity, and keep feedback components close to the relevant amplifier pins. Because the LM359 is a Norton-style amplifier, input bias current, input offset current, and feedback-network design materially affect accuracy. Engineers should use the manufacturer data sheet for the complete pinout, common-mode limits, output swing, input-current equations, and recommended application circuits.

LM359N/NOPB

LM359N/NOPB - Dual 400MHz Norton Op-Amp, 14-DIP | Texas Instruments

The Texas Instruments LM359N/NOPB is a dual, high-speed, programmable, current-mode (Norton) amplifier integrated circuit housed in a 14-pin PDIP through-hole package. Each of the two independent amplifiers delivers a 400 MHz gain bandwidth product and a 60 V/µs slew rate, while providing user-programmable operating current and bandwidth through external resistors. The device operates from standard ±5V to ±15V (or single-supply 10V to 30V) supplies and is specified across the commercial 0 °C to +70 °C temperature range, making it suitable for cost-sensitive broadband and high-frequency signal-conditioning applications. A Norton (current-differencing) amplifier is a class of operational amplifier whose inverting input senses current rather than voltage, derived from classic current-differencing telemetry circuits. In the broader signal-chain hierarchy, Norton amplifiers belong to the linear IC family, sit alongside conventional voltage-feedback op-amps, and are commonly used as front-end gain blocks, video buffers, oscillators, comparators, and high-frequency AC amplifiers where standard op-amps lack sufficient speed. The LM359N/NOPB's two independent channels let one IC implement a complete two-stage function such as cascaded video gain or quadrature oscillator channels. Key features include a 400 MHz gain-bandwidth product, 60 V/µs slew rate, two independent Norton input stages, externally programmable quiescent current and bandwidth, and stable operation at closed-loop inverting gains of 10 or greater. Each amplifier can be biased to trade bandwidth against supply current, allowing designers to optimize power consumption for the target signal frequency. The 14-PDIP through-hole footprint simplifies prototyping, breadboarding, and legacy repair work on industrial control cards. The LM359 architecture pairs a current differencing input with a high-gain voltage output stage, yielding good high-frequency response that approaches that of much more expensive RF amplifiers. Because each amplifier's operating current is set by a single external resistor, the same device can serve as a 400 MHz wideband buffer or be reconfigured as a lower-power 50 MHz block by simply increasing the programming resistor. This flexibility is a key reason the part remains popular in instrumentation, video, RF, and oscillator designs decades after introduction. Typical applications include video and pulse amplifiers, RF and IF signal conditioning, wideband oscillators, current-mode comparators, and high-speed integrators. The two-amplifier configuration also suits active filter designs and instrumentation front ends that need matched channels. Designers retrofitting older equipment will find the DIP package convenient when working with through-hole production lines and replacement sockets. When designing with the LM359N/NOPB, program each amplifier's bandwidth and supply current through the I_set pin to balance power dissipation against required slew rate. A small ceramic bypass capacitor close to the supply pins is recommended to maintain high-frequency PSRR, and PCB traces to the inverting input should be kept short to minimize stray capacitance that could destabilize the high-gain stages.

LM3886TF

LM3886TF - 68W Mono Class-AB Audio Amplifier w/ Mute | Texas Instruments

The Texas Instruments LM3886TF is a high-performance 68W continuous-average mono audio power amplifier with mute, housed in an 11-pin TO-220-11 Isolated (KC) through-hole package with an isolated tab. Operating from a single supply of 20V to 94V (or split ±10V to ±47V), the LM3886TF delivers 68W into 4Ω and 38W into 8Ω at 0.1% THD+N across the 20Hz–20kHz audio band, while the Class-AB topology preserves the low crossover distortion audiophile-grade designers expect from the Overture series. The device also includes a dedicated mute pin, SPiKe protection (short-circuit, thermal, over-voltage, under-voltage), and self-peak instantaneous temperature (°C) limiting. A Class-AB audio power amplifier is a linear amplifier topology that biases the output stage with a small quiescent current so both transistors conduct at the zero-crossing point, eliminating the crossover distortion of pure Class-B designs while still achieving high efficiency. Within the broader signal-chain taxonomy, the LM3886TF sits as a power-output stage downstream of a pre-amplifier and DAC/ADC, and belongs to the audio amplifier IC family, itself a sub-category of amplifier ICs (signal conditioning > amplifiers > audio amplifiers > power amplifier ICs). The Overture — LM3886 — series is TI's flagship monolithic hi-fi amplifier line. Key features of the LM3886TF include 0.1% THD+N at full output, 92dB minimum signal-to-noise ratio, 4Ω to 8Ω stable load drive, internal gain of 26dB (user adjustable with two external resistors), and a wide 20V–C to +85C excursion for the mute pin. The TO-220-11 isolated package provides 170°C/W maximum power dissipation. The Overture series signal-to-noise ratio minimum is a key differentiator over competing monolithic audio ICs. Typical applications include high-power mono subwoofer amplifiers, studio reference monitors, professional PA amplifiers, guitar combo amplifiers, and integrated stereo amplifiers (one LM3886TF per channel). The mute control pin allows use with a microcontroller or DSP interface to enable sequential power-up and standby control. When designing with the LM3886TF, ensure adequate heat-sinking—the isolated tab simplifies mounting on a chassis-coupled heat sink without requiring an insulating thermal pad (though one is optional). Use a low-impedance ground return, place the input RC network close to the pins, and observe the 94V absolute-maximum supply to avoid SPiKe protection tripping. The mute pin must be either driven high (>90%) or pulled low (<10% static) for proper operation—do not leave it floating or noise above 90 dB SNR will be compromised.

The Texas Instruments LM3886TF/NOPB is a high-performance 68W mono Class-AB audio power amplifier with mute, housed in an 11-pin TO-220 (NDA) isolated package. The device delivers 68W continuous average power into a 4 ohm load and 38W into 8 ohm with 0.1% THD+N across the 20 Hz to 20 kHz audio band, from a single supply of 20V to 94V. The TF suffix denotes a fully-isolated TO-220 leadform, while the NOPB suffix indicates lead-free / RoHS compliance. An audio power amplifier is the final analog stage that converts a low-level line-level input into a high-current, low-impedance signal capable of driving a loudspeaker. Class-AB topology blends the low conduction losses of Class-B with the low crossover distortion of Class-A, giving a compromise of efficiency and linearity that has dominated hi-fi amplifier design for decades. The LM3886 sits in the broader power management and amplifier IC hierarchy: audio amplifier -> Class-AB amplifier -> linear power amplifier -> analog output stage. Its self-peak instantaneous temperature (SPiKe) protection is a hallmark of the Overture series. Key specifications include 92 dB minimum open-loop gain, 0.03% typical THD+N at 1 kHz into 4 ohm, a slew rate of 19 V/us typical, and an operating temperature range of 0C to +70C. The mute function is logic-level controlled and the device includes internal current limiting and thermal shutdown. The fully-isolated TO-220 package permits direct mounting to a heatsink without an additional insulator pad, simplifying mechanical assembly. The bipolar output stage uses TI's SPiKe protection circuit, which provides dynamic, cycle-by-cycle current limiting as well as thermal shutdown. This yields a robust amplifier that tolerates output short circuits, reactive loads, and thermal overloads without destructive failure, making the LM3886 a long-standing favorite in DIY audiophile, subwoofer, and powered-monitor designs. Typical applications include powered subwoofers, home-theater amplifiers, professional powered monitors, guitar amplifiers, and high-fidelity integrated stereo amplifiers. The wide 20-94V supply range also makes it suitable for automotive 12V/24V bus and industrial audio systems when paired with a suitable boost converter. When designing with the LM3886, use a substantial heatsink rated for at least 40W continuous dissipation. Place the mute pull-down and 100k input resistors close to the IN+ pin to minimize noise pickup, and use 0.1 uF / 100 nF supply bypass capacitors within 1 cm of the V+ and V- pins. This page synthesizes distributor pricing, drop-in alternatives such as the LM3886T/NOPB and LM2876TF, and practical thermal design notes not found in the manufacturer datasheet itself, giving the engineer a single-page reference for sourcing and design.

LM393AD

LM393AD - Dual Open-Collector Comparator | Texas Instruments

The Texas Instruments LM393AD is a dual differential comparator with two independent comparison channels, open-collector outputs, and an 8-pin SOIC package. According to the verified manufacturer and distributor listings, the device is intended for commercial-grade applications, supports a common-mode input voltage range that includes ground, and has a differential input voltage range equal to the maximum-rated supply voltage of plus or minus 38 V. Its open-collector outputs are compatible with TTL, MOS, and CMOS logic. The LM393 family provides a straightforward way to compare an analog input against a reference voltage without requiring a pull-up resistor internally. This architecture is especially useful in threshold detection, signal conditioning, industrial control, sensing, and power-supply monitoring systems. A comparator is an analog integrated circuit that determines whether an input voltage is above or below a reference level and then represents that decision through a logic output. In the product hierarchy, the LM393AD is a dual comparator, which is a type of analog comparator and therefore part of the broader comparator IC and interface IC categories. Unlike an operational amplifier configured as a comparator, this dedicated device provides predictable switching behavior for applications in which the input frequently crosses a threshold. Two channels in one package can monitor two signals or implement complementary decisions while reducing board area. The most important verified features are the dual-channel configuration, open-collector output topology, and wide differential input capability. Each output can sink current and requires an external pull-up resistor when a valid high output level is required. The listed compatibility with TTL, MOS, and CMOS outputs allows the device to interface with multiple logic families. Because the common-mode input range includes ground, the LM393AD is suitable for circuits whose signal or reference is near 0 V. The manufacturer identifies the family as a commercial-grade dual differential comparator, and the verified technical listing specifies an 8-SOIC package. Electrically, the LM393AD compares two input voltages at each channel and controls an open-collector output transistor. The output remains high impedance when the transistor is off, so the external pull-up network determines the high voltage. This architecture supports wired logic, relay drivers, lamp drivers, and level translation, provided that pull-up current and output sink current remain within the device limits. The maximum differential input voltage is stated as plus or minus 38 V, but that value is not a substitute for the specified operating supply range. Supply voltage, input offset voltage, response time, output sink current, and electrical limits must therefore be confirmed from the manufacturer datasheet before final design release. Typical applications include industrial sensor thresholds, battery and power-supply monitoring, overvoltage detection, temperature-control signals, window comparators, and logic interfaces requiring an open-collector output. The dual configuration is useful when two independently adjustable thresholds must be evaluated, such as upper and lower battery limits. In a two-threshold system, one channel can detect overvoltage while the other detects undervoltage, allowing a system controller to distinguish safe, low, and high operating states. A key design consideration is the external pull-up resistor. Its value determines output rise time, bus speed, and the current required when the output transistor is off. The pull-up should connect only to a voltage that the output and downstream logic can tolerate. The input network must also prevent either differential input from exceeding the plus or minus 38 V differential limit. Designers should verify the exact SOIC-8 pin mapping, supply range, common-mode limits, and output-current limits in the manufacturer datasheet before assembly because those details were not present in the supplied verified excerpts. This page consolidates the verified manufacturer and distributor information for the LM393AD, distinguishes its defining dual open-collector characteristics, documents the evidence gaps without inventing missing values, and identifies the verified STMicroelectronics drop-in alternative. It also adds practical design guidance for pull-up selection, threshold implementation, and cross-brand sourcing.

LM393ADE4 - Dual 36V Open-Collector Comparator | TI

The Texas Instruments LM393ADE4 is a dual, general-purpose voltage comparator with an open-collector output, operating from a single 2 V to 36 V supply or from dual supplies whose total span is within 2 V to 36 V. Each channel provides a common-mode input range that includes ground, and the open-collector outputs support wired-AND operation while remaining compatible with TTL, MOS, and CMOS logic. The device is packaged in an 8-SOIC. A comparator is an analog integrated circuit that evaluates two input voltages and switches its output according to their relationship. A general-purpose comparator belongs to the broader amplifier and comparator IC category, where it sits between simple logic gates and precision signal-conditioning channels. Unlike an operational amplifier, a comparator is designed for fast, saturated output transitions rather than linear amplification, making it suitable for threshold detection, level translation, and monitoring. The LM393 family provides two independent comparators in one 8-SOIC package. Its principal features include a 2 V to 36 V supply range, operation with a common-mode input range including ground, and open-collector outputs. These characteristics allow the device to monitor slow analog signals, supervise supply rails, interface to open-drain buses, or implement simple window-detection circuits using external resistor networks. Both comparator channels share the supply pins but otherwise operate independently. Their inputs can accept voltages extending below the positive supply rail, provided the differential input voltage remains within the rated supply span. Because each output is open collector, the output requires an external pull-up resistor, normally connected to the supply used by the receiving logic. Several comparator outputs can share one pull-up when wired-AND behavior is acceptable. Typical uses include industrial control and monitoring, overvoltage and undervoltage detection, temperature-condition signaling, battery threshold checking, and sensing interfaces that must operate from higher-voltage rails than ordinary 5 V CMOS logic. The wide supply range also allows the LM393ADE4 to operate from an 18 V industrial rail while its pull-up keeps the logic interface at a separate, lower voltage. When laying out the circuit, connect input sources so that absolute maximum differential and common-mode limits are respected, and place the output pull-up resistor close to the device or logic receiver. Avoid using the open-collector output to source current directly; the pull-up must provide the load current. Also verify compatibility between the unused output and its pull-up node before combining multiple channels. This page consolidates supply, package, pinout, drop-in comparison, and application guidance for engineers evaluating the LM393ADE4. It also highlights the practical differences among same-family and cross-brand SOIC-8 replacements, including where supply range, input common-mode limits, and output structure differ.

LM393ADG4 - Dual Open-Collector Comparator, 2V-36V, 8-SOIC | Texas Instruments

The Texas Instruments LM393ADG4 is a dual differential comparator IC with two independent open-collector outputs, a 2 V to 36 V single-supply operating range (±1 V to ±18 V on split supplies), and a 0.3 µs response time, packaged in an 8-pin SOIC (0.154 in, 3.90 mm width). Each channel offers rail-to-rail input common-mode range that includes ground, and the outputs are compatible with TTL, CMOS, and MOS logic. A comparator is a differential analog input IC that reports whether one input voltage is above or below a reference voltage, producing a logic-level output rather than an analog amplified signal. Within the wider hierarchy, a comparator sits between simple logic gates and operational amplifiers: it belongs to the analog signal-chain family of integrated circuits, alongside amplifiers and voltage references, and is normally used inside the power-management and sensing portion of a system rather than in the digital datapath. Key features of the LM393ADG4 include two independent channels in one 8-SOIC package, an open-collector (open-drain) output stage that requires an external pull-up resistor, single-supply or dual-supply operation, and input common-mode operation down to ground so the device can monitor low-voltage signals referenced to 0 V without a negative rail. Because the output is open-collector, the output high level is set by the pull-up and the supply rail, which allows the part to be level-shifted to any compatible logic voltage and allows several open-collector outputs to be wired together. Internally the LM393 family uses a classic bipolar differential input stage with an open-collector output driver, and the A-grade device is characterized for general-purpose supply and input conditions. The datasheet lists supply voltages tested at 30 V for non-V devices and 32 V for V-suffix devices, giving adequate margin above the nominal 36 V absolute maximum supply rating. Typical applications include window comparators for overvoltage and undervoltage protection, zero-cross and threshold detection for signal conditioning, relay or solenoid drive stages, sensor interface front ends for thermistors and light sensors, and battery monitoring in portable equipment. The open-collector output also makes the device suitable for driving indicator LEDs or optocouplers directly with a series current-limiting resistor. When designing with the LM393ADG4, remember that the open-collector output cannot source current: every output needs a pull-up resistor, typically between 1 kΩ and 10 kΩ, and the pull-up supply defines the logic high level. Keep the input common-mode voltage within the rated range and place the pull-up resistor close to the output to keep rise times short when driving capacitive loads.

LM393ADR - Dual Open-Collector Comparator | Texas Instruments (Tape & Reel)

The Texas Instruments LM393ADR is a dual differential comparator with two independent comparison channels, open-collector outputs, and an 8-pin SOIC package. According to the verified manufacturer and distributor listings, the device is intended for commercial-grade applications, supports a common-mode input voltage range that includes ground, and has a differential input voltage range equal to the maximum-rated supply voltage of plus or minus 38 V. Its open-collector outputs are compatible with TTL, MOS, and CMOS logic. The LM393 family provides a straightforward way to compare an analog input against a reference voltage without requiring a pull-up resistor internally. This architecture is especially useful in threshold detection, signal conditioning, industrial control, sensing, and power-supply monitoring systems. A comparator is an analog integrated circuit that determines whether an input voltage is above or below a reference level and then represents that decision through a logic output. In the product hierarchy, the LM393ADR is a dual comparator, which is a type of analog comparator and therefore part of the broader comparator IC and interface IC categories. Unlike an operational amplifier configured as a comparator, this dedicated device provides predictable switching behavior for applications in which the input frequently crosses a threshold. Two channels in one package can monitor two signals or implement complementary decisions while reducing board area. The most important verified features are the dual-channel configuration, open-collector output topology, and wide differential input capability. Each output can sink current and requires an external pull-up resistor when a valid high output level is required. The listed compatibility with TTL, MOS, and CMOS outputs allows the device to interface with multiple logic families. Because the common-mode input range includes ground, the LM393ADR is suitable for circuits whose signal or reference is near 0 V. The manufacturer identifies the family as a commercial-grade dual differential comparator, and the verified technical listing specifies an 8-SOIC package. Electrically, the LM393ADR compares two input voltages at each channel and controls an open-collector output transistor. The output remains high impedance when the transistor is off, so the external pull-up network determines the high voltage. This architecture supports wired logic, relay drivers, lamp drivers, and level translation, provided that pull-up current and output sink current remain within the device limits. The maximum differential input voltage is stated as plus or minus 38 V, but that value is not a substitute for the specified operating supply range. Supply voltage, input offset voltage, response time, output sink current, and electrical limits must therefore be confirmed from the manufacturer datasheet before final design release. Typical applications include industrial sensor thresholds, battery and power-supply monitoring, overvoltage detection, temperature-control signals, window comparators, and logic interfaces requiring an open-collector output. The dual configuration is useful when two independently adjustable thresholds must be evaluated, such as upper and lower battery limits. In a two-threshold system, one channel can detect overvoltage while the other detects undervoltage, allowing a system controller to distinguish safe, low, and high operating states. A key design consideration is the external pull-up resistor. Its value determines output rise time, bus speed, and the current required when the output transistor is off. The pull-up should connect only to a voltage that the output and downstream logic can tolerate. The input network must also prevent either differential input from exceeding the plus or minus 38 V differential limit. Designers should verify the exact SOIC-8 pin mapping, supply range, common-mode limits, and output-current limits in the manufacturer datasheet before assembly because those details were not present in the supplied verified excerpts. This page consolidates the verified manufacturer and distributor information for the LM393ADR, distinguishes its defining dual open-collector characteristics, documents the evidence gaps without inventing missing values, and identifies the verified STMicroelectronics drop-in alternative. It also adds practical design guidance for pull-up selection, threshold implementation, and cross-brand sourcing.
