LM339NG

LM339NG - 3-36V Quad Open-Collector Comparator | onsemi

The onsemi LM339NG is a four-channel general-purpose analog comparator with a 3 V to 36 V single-supply operating range, open-collector CMOS/TTL-compatible outputs, and a 14-pin PDIP package. Each channel compares two input voltages, making the device suitable for level detection, low-level sensing, memory applications, threshold control, and industrial interface circuits. The LM339NG supports single or split supply operation. An analog comparator is an integrated circuit that determines whether an input voltage is above or below a reference voltage. In the broader electronics hierarchy, a comparator belongs to the analog IC and signal-conditioning category, where it converts a continuously varying voltage relationship into a logic-level decision. Unlike an operational amplifier, a comparator is optimized for fast switching between output states rather than linear amplification. The four independent LM339NG channels combine a wide supply-voltage range with low input bias current. Verified sources report a typical input bias current of 25 nA, a typical input offset current of ±5 nA, and an input offset voltage of 1.3 mV. The distributor descriptions identify the outputs as open collector, allowing the output stage to sink current rather than actively sourcing it. This architecture requires an external pull-up resistor when the comparator must produce a valid high level. With a response time of approximately 1.3 microseconds, the LM339NG is suitable for general-purpose detection rather than very high-speed signal comparison. Its 14-pin PDIP construction supports through-hole assembly and is useful in industrial control equipment, automotive electronic modules, consumer appliances, memory-control circuits, and laboratory interface boards. The package is also readily inspected or replaced during maintenance. A key design consideration is the open-collector output. Each output requires a pull-up resistor to the appropriate logic supply, and the pull-up voltage must not exceed the applicable device limits. Input common-mode range, output saturation, input protection, and supply-current behavior should be checked against the manufacturer datasheet before operation near the supply extremes. This page consolidates verified distributor information, source-linked specifications, practical application guidance, and cautious drop-in alternatives. It also distinguishes confirmed LM339NG characteristics from attributes that still require full datasheet or application-specific verification before production use.

LM339NSRG4 - Quad Open-Collector Comparator | Texas Instruments
LM339NSRG4

LM339NSRG4 - Quad Open-Collector Comparator | Texas Instruments

Texas Instruments LM339NSRG4 is a quad differential voltage comparator containing four independent comparator sections, a maximum offset voltage of 9 mV, and a response time of 1300 ns in a 14-pin SOIC package. It supports single-supply or dual-supply operation and is designed for general-purpose signal comparison applications. Each channel can compare a differential input pair against a common reference, while the open-collector outputs allow wired logic, pull-up resistors, and flexible system-level voltage interfacing. A voltage comparator is an analog interface IC that evaluates two input voltages and changes its output state when the difference between them crosses a defined threshold. The LM339 belongs to the broader comparator and signal-conditioning hierarchy, where its four channels can implement threshold detection, zero-crossing detection, window comparison, saturation sensing, and basic control decisions. Its multi-channel architecture also allows one package to monitor several independent conditions without requiring four separate comparator devices. Key characteristics include operation from a single supply or from dual supplies, a tested supply rating of 30 V for LM339 versions and up to 32 V for non-V devices, low supply-current drain that is independent of supply voltage, and a typical supply-current drain of 0.8 mA. The open-collector output architecture requires an external pull-up, providing flexibility in output voltage and bus-level compatibility. The four channels share supply pins but otherwise retain independent input and output connections. The LM339 architecture is suited to low-cost analog decision circuits because its inputs respond to a wide common-mode range while the open-collector outputs remain electrically flexible. Because bipolar comparators can draw input bias current, source impedance should be limited where offset errors matter. Open-collector outputs can also expose the output node to more than one driver, so wired-AND logic requires careful pull-up selection and a review of output sink-current limits before several comparators share a node. Typical uses include industrial sensor interfaces, overvoltage and undervoltage monitors, temperature-threshold circuits, motor-control interfaces, power-supply supervision, and general industrial control systems. It is particularly useful when several independent comparisons must be performed within a limited board area and a 14-pin surface-mount footprint is preferred over through-hole DIP packaging. When designing around the LM339NSRG4, include a pull-up resistor on every open-collector output, keep input common-mode voltage within the device operating limits, and account for input bias current when using high-impedance sensors. Place bypass capacitance close to the supply pins and route sensitive comparison inputs away from switching nodes and high-current return paths. This page organizes the LM339NSRG4’s key electrical characteristics, application guidance, pin-level information, and carefully qualified replacement options. It is intended to help engineers confirm footprint compatibility, assess threshold accuracy and response time, and plan the external components required by an open-collector comparator design.

LM339PT - 4-Channel Open-Collector Comparator | STMicroelectronics
LM339PT

LM339PT - 4-Channel Open-Collector Comparator | STMicroelectronics

The STMicroelectronics LM339PT is a low-power quad voltage comparator containing four independent comparison channels in a 14-pin TSSOP package. Each channel supports single-supply or split-supply operation and uses an open-collector output, allowing the outputs to be wired together for wired-AND behavior. The verified product data identifies a 1 V to 16 V supply range, a maximum input offset voltage of 2 mV for the A-grade device family, and compatibility with CMOS, DTL, ECL, MOS, open-collector, and TTL logic. A voltage comparator is an analog integrated circuit that compares two input voltages and changes its output state according to their relationship. The LM339 belongs to the comparator hierarchy within analog and mixed-signal semiconductors. Its four independent channels can perform threshold detection, overvoltage monitoring, window comparison, zero-crossing detection, and general-purpose signal conditioning. Unlike a digital logic gate, the comparator evaluates continuously varying analog voltages at its inputs. The main feature of the LM339PT is its combination of four independent open-collector comparators in one compact TSSOP-14 package. Its low-power design is suitable for battery-powered equipment, while the broad supply-voltage range supports industrial control and instrumentation systems. The open-collector architecture requires an external pull-up resistor and can interface with CMOS or TTL logic. The verified distributor description also reports a propagation delay of 1.3 µs, making the device suitable for moderate-speed threshold and protection functions rather than ultra-high-speed applications. Each comparator channel has two input pins, an output, and access to the device ground and supply pins. The outputs are open-collector rather than push-pull, so an output can sink current while remaining high-impedance when inactive. Pull-up resistors are therefore required on every used output. Connecting outputs together requires compatible pull-up arrangements and careful review of the maximum sink-current and voltage limits. The device does not provide a latch function, so applications requiring state retention normally add external feedback or latch circuitry. Typical uses include DC overvoltage detection, power-supply sequencing, sensor threshold switching, battery monitoring, industrial control interfaces, and logic-level conversion. Split-supply operation allows the comparator to evaluate signals around ground, while single-supply operation is useful when all measured signals remain above the common-mode limits. Because the outputs are open collector, the device can also connect to buses such as SMBus or I2C where wired-AND behavior is required, provided the electrical and timing requirements of the specific bus are satisfied. Designers should account for input common-mode range, output pull-up resistance, supply decoupling, and the behavior of the open-collector output at temperature extremes. Place the device close to the protected signal and provide a stable ground reference. Avoid relying on an output to source current, and select a pull-up voltage compatible with both the comparator output ratings and the driven logic family. The TSSOP-14 package supports compact PCB layouts, but pin-1 orientation must be checked carefully because closely spaced leads can complicate hand rework. This product page consolidates verified distributor availability and pricing, package information, same-package cross-references, and practical design guidance. It also distinguishes drop-in replacements from devices that differ in package or temperature grade, helping engineers make a replacement decision without assuming that every similarly named LM339 variant is electrically and mechanically interchangeable.

LM339PW - 4-Channel 36V Open-Collector Comparator | Texas Instruments

The Texas Instruments LM339PW is a four-channel general-purpose differential comparator operating from a 2 V to 36 V single supply, with an open-collector output and a 14-pin TSSOP package. Each independent comparator compares two analog inputs and produces a logic-level indication of their relationship. The family supports a supply range of 2 V to 36 V, a 300 ns response time, and operation where the common-mode input voltage range includes ground. A differential comparator is an analog-to-digital decision component that compares two voltage inputs and changes its output when one input crosses the other. A quad comparator such as the LM339PW integrates four independent channels, making it part of the comparator IC hierarchy and the broader interface IC and semiconductor categories. Its open-collector outputs require an external pull-up resistor, allowing the output voltage, rise time, and interface standard to be selected by the system designer. The verified LM339 family information highlights a maximum rating of up to 38 V, an HBM ESD rating of 2 kV, a low input offset of 0.37 mV, a low input bias current of 3.5 nA, and a typical supply current of 200 µA per comparator. A response time of 1 µs is also listed for the family. These characteristics make the device useful for level detection, threshold comparison, open-collector bus signaling, and industrial control functions where input signals can approach ground. Each of the four channels is independent, so the device can perform unrelated comparisons without coupling the logic states of different channels. The open-collector architecture can sink output current while the external pull-up establishes the high state, which is useful for wired logic, relay-driver interfaces, and legacy TTL, MOS, or CMOS-compatible systems. Because output rise time depends on the pull-up resistance and total node capacitance, timing analysis must include the external network rather than relying only on the comparator response time. Typical applications include industrial sensor-threshold monitoring, battery and power-supply protection, overvoltage detection, window comparators, and four-channel level translation. The ground-referenced common-mode capability is particularly useful for detecting the presence or absence of a signal from a 12 V or 24 V industrial sensor. A pull-up can also connect the open-collector outputs to an appropriate supply, allowing multiple comparators to form a wired signal function where the application and device specifications permit it. When designing the PCB, place the pull-up resistor close to the open-collector output and route the node away from high-current switching paths. Decoupling capacitors should connect the supply and ground pins with a short return path. Because the package has no exposed thermal pad and the device can operate across a wide voltage range, engineers should verify the maximum differential input voltage, output current, and dissipation conditions against the manufacturer datasheet. This page consolidates verified distributor and manufacturer information with package guidance, application analysis, commercial questions, and drop-in replacement details. It is intended to support faster component selection while clearly identifying specification fields, pricing, and pin-level details that still require confirmation from the appropriate manufacturer documentation.

LM339PWG4 - Quad Open-Collector Comparator | Texas Instruments

The Texas Instruments LM339PWG4 is a quad differential comparator containing four independent voltage-comparison channels, an open-collector output architecture, and a 14-pin TSSOP package. Each comparator supports single-supply or dual-supply operation, with a maximum supply-voltage rating of 38 V, low input offset voltage of 0.37 mV, low input bias current of 3.5 nA, and typical supply-current consumption of 200 uA per comparator. The LM339 family provides common-mode input operation that includes ground and outputs compatible with TTL, MOS, and CMOS logic. A differential comparator is an analog integrated circuit that compares two input voltages and produces a binary result indicating which input is higher. The LM339 belongs to the comparator hierarchy within analog and mixed-signal semiconductors. Four independent channels allow one package to perform several threshold, level, window, or sensing functions. Its open-collector outputs require an external pull-up resistor, allowing the output voltage to be raised to a logic supply selected by the system designer. Key features include four independent comparator channels, a wide 36 V operating supply range indicated by the manufacturer’s related part listing, and a 38 V maximum rating. The device offers a typical total supply-current drain of 0.8 mA, a low input offset of 0.37 mV, and an input bias current of 3.5 nA. Its open-collector architecture is useful for wired-AND buses, relay-driver interfaces, and systems that need a pull-up voltage different from the comparator supply. The LM339 architecture is suited to general-purpose precision comparison rather than high-speed waveform discrimination. The manufacturer identifies LM339B, LM2901B, LM339, LM239, and LM139 as related quad differential comparators and states that the B-version is a drop-in replacement for the earlier A- and V-version families. Open-collector outputs can sink logic current but cannot actively drive a high voltage without a pull-up network. Typical applications include sensor-threshold conditioning, battery and power-supply monitoring, industrial control interfaces, window comparators, LED status signaling, and open-collector alarm or relay-control signaling. The four-channel organization can also reduce package count when a board needs independent comparisons for multiple sensors or rails. In circuits sharing an input source, each channel can compare that source against a different threshold. Designers should treat the output as a sinking device rather than a push-pull logic driver. Place the pull-up resistor close to the relevant output, account for rise time when driving capacitive loads, and use the pin-description table in the Texas Instruments datasheet when assigning PCB tracks. Input common-mode range, output pull-up voltage, and total supply dissipation must be checked against the intended application. This product page combines the manufacturer’s device characteristics with engineering-focused comparisons, application guidance, pin-related cautions, and a strict same-package replacement analysis. It is designed to help engineers determine whether the 14-pin TSSOP LM339PWG4 fits a precision comparator design without assuming that a superficially similar part is electrically or mechanically interchangeable.

LM339PWRE4 - Quad 36V Differential Comparator | Texas Instruments

Texas Instruments LM339PWRE4 is a quad differential comparator with an open-collector output, operating from a single 2 V to 36 V supply or from dual supplies, and packaged in a 14-pin TSSOP. Each of the four channels provides independent comparison of two input voltages, making the device suitable for threshold detection, level translation, and analog signal conditioning. A comparator is a differential analog input device that changes its output state when one input becomes higher than the other. The LM339 belongs to the comparator hierarchy within analog integrated circuits and combines four sensing channels in one package. Its open-collector outputs require an external pull-up resistor, allowing the output voltage, rise time, and interface level to be selected by the surrounding circuit. The LM339 family is designed for single-supply or dual-supply operation. The manufacturer identifies a differential input range equal to the maximum-rated supply voltage of plus or minus 38 V, while the common-mode input range includes ground. These characteristics allow the device to monitor signals referenced to a negative rail or systems powered from widely separated supply rails. According to the Texas Instruments product page, the outputs are compatible with TTL, MOS, and CMOS logic. The family also uses low supply current that remains largely independent of supply voltage, making it practical for battery-powered monitoring circuits where every microampere contributes to operating time. The comparison function is particularly useful when a system requires a digital indication of an analog threshold without converting the entire measurement chain to a digital signal. Typical uses include overvoltage and undervoltage detection, sensor threshold switching, window comparators, relay or solenoid drivers, and battery monitoring. Four independent channels can reduce component count in a multi-rail supervisor, while the open-collector architecture permits wired logic, pulled-up alarm outputs, and interfacing to multiple destinations. When laying out a circuit, place input and pull-up components close to the device and keep sensitive comparison nodes away from switching-current paths. Check the input common-mode range, output pull-up voltage, supply sequencing, and channel response time before using the comparator with slow-moving or noisy signals.

Texas Instruments LM339PWRG3 is a quad differential comparator integrated circuit containing four independent voltage comparators. It operates from a single supply of up to 36 V or from dual supplies whose total span is 2 V to 36 V, and it is housed in a 14-pin TSSOP package. Each channel supports an open-collector output compatible with TTL, MOS, and CMOS logic. The device is intended for general-purpose threshold detection, signal conditioning, and industrial control applications. A comparator is an analog integrated circuit that compares two input voltages and changes its output state when one input crosses the other. The LM339 family belongs to the comparator hierarchy within analog ICs and broader semiconductor signal-processing devices. Its four independent channels allow a single package to implement multiple sensing, protection, or level-conversion functions without requiring four separate single-comparator packages. The LM339 family is designed for wide supply-voltage operation and common-mode input ranges that include ground. According to the Texas Instruments product page, the B-version is a drop-in replacement for LM239, LM339, and LM2901 devices, while the differential input range can equal the maximum-rated supply voltage of 38 V. Open-collector outputs allow wired-AND operation and require an external pull-up resistor. The outputs are designed to drive TTL, MOS, and CMOS-compatible logic. The verified specifications identify a maximum input offset of 0.37 mV, an input bias current of 3.5 nA, and a supply current of 200 uA per comparator. A faster response is also listed as a family improvement. These characteristics make the LM339 useful when a system must compare low-level sensor signals against adjustable references while tolerating substantial supply variation. The open-collector architecture is especially useful where multiple channels must share a pull-up or where a wired fault-detection signal is required. Typical uses include industrial control systems, battery-powered monitoring equipment, sensor threshold circuits, window or level comparators, overvoltage detection, and general digital interface conditioning. The wide operating range is valuable in industrial systems, while the low 200 uA per-comparator supply current supports low-power monitoring designs. Each internal comparator is electrically independent, allowing unused channels to be configured according to the manufacturer datasheet. Layout should preserve a low-impedance ground reference and keep input and feedback traces short because comparison accuracy can be affected by input offset, bias current, and parasitic coupling. Open-collector outputs require suitable pull-up resistors and adequate logic-level current margin. Review the manufacturer pin-description table before assigning tracks because input, output, supply, and ground functions are distributed across the 14-pin TSSOP. This page combines the LM339 family specifications with practical interpretation of supply range, input behavior, output compatibility, package construction, application fit, and replacement considerations. It helps engineers compare the device against closely related TI parts while keeping PCB footprint, logic interface, and analog performance requirements in view.

LM339PWRG4 - Quad Differential Comparator | Texas Instruments

Texas Instruments LM339PWRG4 is a general-purpose quad differential comparator containing four independent comparator channels in a 14-pin TSSOP package. It accepts single-supply or dual-supply operation, uses open-collector outputs, and supports input voltages extending to ground on the negative side. The device is suited to applications that compare two analog signals and require a logic-compatible, low-saturation output rather than a rail-to-rail push-pull output. A differential comparator is an analog integrated circuit that evaluates the relationship between two input voltages and produces a binary result. When the voltage applied to the non-inverting input exceeds the voltage applied to the inverting input, the corresponding output changes state according to the device's output circuit. The LM339 belongs to the comparator hierarchy within interface ICs and combines four channels in one package, reducing component count in multi-threshold, window-detection, and control systems. The principal advantages of the LM339PWRG4 are its four-channel integration, low supply-current drain, low input-bias current, and open-collector outputs. According to the manufacturer datasheet, the supply-current drain is typically 0.8 mA and is independent of supply voltage. Each output can sink useful logic current while remaining compatible with TTL, MOS, and CMOS systems. A pull-up resistor is required when the output is used as a wired logic node. The comparator's architecture supports single or dual supplies, with a wide operating-voltage range and a maximum-rated supply of 30 V for non-V devices. The common-mode input range includes ground, allowing the device to monitor signals near 0 V. The differential input-voltage range can equal the maximum-rated supply voltage. These characteristics are useful in power-supply control, battery monitoring, industrial sensing, and analog signal conditioning where input levels may exceed conventional logic supply ranges. Typical uses include overvoltage and undervoltage monitoring, current-limit detection, sensor threshold comparison, open-collector alarm signaling, and multi-level battery supervision. Because each of the four channels can compare a separate signal pair, systems can implement several protection functions while sharing the same device. Input and output behavior must be checked against the operating supply, source impedance, pull-up network, and required switching speed. The primary design consideration is the open-collector output. Add a suitable pull-up resistor to the positive supply or another valid logic rail, and confirm that its maximum current and switching speed suit the connected logic family. Avoid floating outputs, account for input offset and common-mode limits, and design signal paths so that nearby switching nodes do not disturb a comparison threshold. The 14-TSSOP package also requires a thermal pad-free layout with adequate solder-joint fillets and board-edge clearance. This page consolidates manufacturer specifications, pin-package details, sourcing guidance, comparison parameters, and practical application notes for engineers evaluating the LM339PWRG4. It also distinguishes direct replacements from options that require electrical or package verification, helping prevent a superficially similar part from causing unexpected logic-level or output-stage incompatibilities.

LM339QT - Low-Power Quad Open-Collector Comparator | STMicroelectronics

The STMicroelectronics LM339QT is a low-power, general-purpose quad voltage comparator containing four independent comparator channels with open-collector outputs in a 16-QFN package measuring 3 x 3 mm. It operates from a single positive supply, supports input voltages ranging from 0 V to VCC − 1.5 V, and provides a typical supply current of 1.1 mA for the complete four-channel device. A voltage comparator is a semiconductor device that compares two input voltages and produces a logic-level output indicating which input is higher. The LM339QT belongs to the comparator hierarchy within analog and mixed-signal integrated circuits. Its four open-collector channels can be used independently, allowing several threshold, sensing, window-detection, or protection functions to be implemented in one compact package. Open-collector outputs also provide flexibility for wired logic, level shifting, and interface designs when an external pull-up is used. Key characteristics include low power consumption, an input offset voltage specified as low as 2 mV maximum for the related LM339A, LM239A, and LM139A precision versions, and input bias current listed as 25 nA in the product listing. The device is compatible with CMOS, DTL, ECL, MOS, open-collector, and TTL logic environments. Each channel provides substantial flexibility in voltage comparison because the inputs can operate across the supply range while the output stage operates from the positive supply. The open-collector output architecture is a central technical feature. Unlike a totem-pole output, an open-collector transistor can pull the output low but cannot actively drive it high. Designers therefore add a pull-up resistor to establish the high state. Multiple comparator outputs can share a pull-up when the application requires wired-AND behavior. Output speed is not its principal strength; instead, the LM339QT emphasizes low power, wide input common-mode capability, flexible logic interfacing, and four independent channels in one small package. Typical uses include monitoring multiple power rails, detecting overvoltage or undervoltage conditions, comparing sensor outputs with adjustable references, implementing window comparators, generating system-reset signals, and translating between different logic voltage domains. The compact 16-QFN footprint is useful in space-constrained industrial, consumer, and embedded-control designs where four comparison functions are required without allocating separate components. The primary design consideration is the open-collector output. Select an external pull-up resistor to suit the required speed, current, and logic level, and place it close enough to the relevant output to limit rise time and susceptibility to noise. Input filtering may also be necessary when the comparator handles slow or high-impedance signals. Verify absolute maximum voltage, common-mode limits, output-current limits, and timing requirements in the manufacturer datasheet for the final operating environment. This product page combines the exact LM339QT package and headline electrical characteristics with practical interface guidance, sourcing guidance, and a focused comparison of technically relevant alternatives. It is intended to help engineers identify whether the four-channel, low-power, open-collector architecture matches the required voltage sensing and logic interface before committing to a PCB layout.

LM339SNG - Quad Single-Supply Comparator, 14-Pin PDIP

onsemi LM339SNG is a quad voltage comparator integrated circuit with four independent comparison channels, a single-supply architecture, and a 14-pin PDIP package. The LM339SNG is identified as a comparator device covering an 18 V to 36 V operating range, making it suitable for industrial control, instrumentation, power-monitoring, sensor-interface, and threshold-detection circuits. Its four-channel arrangement allows one packaged device to implement several independent switching decisions while reducing component count and simplifying PCB layout. A comparator is an analog integrated circuit that evaluates two input voltages and produces a logic-level output indicating which input is higher. In the broader electronics hierarchy, LM339SNG belongs to the comparator family within analog and mixed-signal semiconductors. Its single-supply operation is useful when the system has one main supply rail, while its open-collector-style output class is commonly used to drive pull-ups, relay drivers, alarm inputs, and digital control logic. The LM339SNG provides four comparator channels in one package. The 14-pin PDIP arrangement gives adequate spacing for through-hole assembly, inspection, and prototype rework, although it occupies more board area than surface-mount equivalents. The device is particularly useful when a design requires multiple analog threshold decisions and the board maker prefers a readily available through-hole package. A single IC can reduce the number of separate packages and simplify routing between sensing and control sections. Typical applications include sensing relay and solenoid drivers, overvoltage and undervoltage detection, window comparators, battery monitoring, level detection, industrial control interfaces, and general-purpose logic threshold circuits. Because comparator outputs are intended to indicate the relative state of two analog inputs, designers should pay attention to input common-mode range, output pull-up requirements, propagation delay, input offset, and supply voltage limits when establishing system behavior. These operating details should be confirmed against the manufacturer datasheet before final qualification. For implementation, place the device close to the signals being compared and keep sensitive analog traces away from fast-switching nodes. Use suitable bypass capacitance near the supply pins, provide the required pull-up network for the outputs, and verify that every signal remains within the device's supported common-mode and supply limits. The 14-pin PDIP package is particularly appropriate for through-hole industrial, educational, and control-board assemblies where mechanical robustness is more important than minimum board area. This product page combines the verified LM339SNG identity and package information with practical guidance on comparator behavior, PCB implementation, application fit, and drop-in alternatives. It is intended to help engineers confirm whether the single-supply quad comparator is appropriate for a new design before committing to a board layout or production build.

Housed in an 8-pin SOIC package, the LM358AD delivers a unity-gain bandwidth of approximately 1.1 MHz, a slew rate of 0.6 V/µs, and supports supply voltages from 3V to 30V single-supply or ±1.5V to ±16V dual-supply. The device is widely used in cost-sensitive analog front-ends where single-supply operation and low quiescent current are essential design constraints. An operational amplifier (op-amp) is a high-gain, DC-coupled electronic voltage amplifier with differential inputs and a single-ended output. Within the broader power management and signal conditioning hierarchy, the LM358AD belongs to the general-purpose op-amp category, sitting between precision instrumentation amplifiers (high accuracy, low noise) and high-speed amplifiers (wide bandwidth, fast slew). Op-amps form the building blocks of analog signal chains: filters, comparators, integrators, transducers, sensor signal conditioners, and active rectifiers. The LM358 family specifically targets single-supply 5V/12V/24V systems that cannot tolerate the negative rail required by legacy op-amps like the LM741. Key features include: 1.1 MHz gain-bandwidth product, 0.6 V/µs slew rate, input common-mode range that includes ground (enabling true single-supply sensing near 0V), low input bias current, internal frequency compensation (no external capacitor required), and ESD protection on the inputs. The output stage can swing to within a few hundred millivolts of the negative rail, although it does not reach the positive rail — meaning the part is not rail-to-rail but is sufficient for most single-supply transducer interfaces. Technically, the LM358AD uses a bipolar junction transistor (BJT) input stage rather than JFET or CMOS, which trades higher input bias current (~45 nA typical) for extremely low input offset voltage drift and predictable behavior across temperature. The two amplifiers share only the power pins; their inputs and outputs are fully independent, allowing asymmetric configurations such as one channel as a comparator and the other as a gain stage. Typical applications include battery-powered sensor signal conditioning, transducer amplifiers, DC gain blocks, active filters, integrators, comparators with hysteresis, and 4–20 mA current loop transmitters. Industrial designs frequently use the LM358AD in 24V PLC analog input modules, while consumer designs use it for white-goods sensor interfaces and IoT battery nodes. When designing with this device, remember that the output cannot swing to the positive rail — typically VOH stops around VCC−1.5V at 10 mA load. Place a 100 nF bypass capacitor close to VCC and ground, and use a feedback resistor of at least 10 kΩ to limit output stage loading.

LM358ADE4

LM358ADE4 - Dual General-Purpose Op Amp | Texas Instruments

Texas Instruments LM358ADE4 is a dual general-purpose operational amplifier with two amplifier circuits in an 8-SOIC package. The identified device operates at a 700 kHz gain-bandwidth product and has a slew rate of 0.3 V/us, providing a practical combination for general-purpose signal conditioning. Its two-circuit arrangement allows one package to implement functions such as buffering, voltage amplification, filtering, comparisons, and differential signal handling. An operational amplifier is an analog integrated circuit that uses high open-loop gain and negative feedback to amplify a voltage difference between its input terminals. In the broader hierarchy, an operational amplifier is a linear amplifier and analog signal-processing IC used within instrumentation, control, sensor, communications, and power-management systems. The LM358 family is associated with two amplifiers per package, making it useful where board area or component count matters. The LM358ADE4 provides a 700 kHz gain-bandwidth product, a 0.3 V/us slew rate, and two amplifier circuits in an 8-SOIC package. The wide SOIC body measures 0.154 inches, or 3.90 mm, in width according to the part listing. These characteristics suit moderate-bandwidth analog signals rather than demanding high-speed waveform or video applications. Each internal amplifier can be configured independently for standard inverting, non-inverting, summing, and feedback-based signal-conditioning circuits. The 8-SOIC package provides widely separated input, output, and power connections on a conventional surface-mount footprint. Its dual-channel architecture reduces the number of packages needed when two independent gain stages, two comparators, or mixed analog functions are required. The device is identified by Texas Instruments as an industry-standard dual operational amplifier, supporting design familiarity and straightforward board-level integration where the LM358 family is already qualified in the design. Typical uses include low-frequency sensor amplification, industrial control signals, audio preamplification, power-supply feedback loops, active filters, and general instrumentation. Two amplifiers in one package can also support comparator-style operation when saturation and switching behavior are acceptable. Because the gain-bandwidth product is 700 kHz, the device is better suited to modest signal bandwidth than precision audio or communications paths requiring substantially faster amplifiers. Design the surrounding feedback network to establish the intended closed-loop gain and bandwidth. Check output swing, input common-mode range, supply voltage, offset, input bias current, and output-current requirements in the manufacturer datasheet before finalizing the circuit. Place input and output components close to their associated pins, maintain a quiet supply path, and check that the selected SOIC footprint, pin orientation, and tube ordering code match the assembly process. This product page combines the exact ordering information, package characteristics, operating bandwidth, pin-compatible family alternatives, and practical design guidance needed to plan an LM358ADE4-based analog circuit before component sourcing and PCB layout.

LM358ADG4

LM358ADG4 - Dual 700kHz Op Amp, 8-SOIC | Texas Instruments

The Texas Instruments LM358ADG4 is a dual, general-purpose operational amplifier with two amplifier circuits in an 8-SOIC package. Its headline characteristics include a 700 kHz gain-bandwidth product, 0.3 V/µs slew rate, input offset voltage of 2 mV, and operation from a single supply up to 16 V. The device is supplied in a tube and is intended for general-purpose signal-conditioning applications rather than precision or high-speed instrumentation. An operational amplifier, commonly called an op amp, is a high-gain differential amplifier used to amplify the difference between two input voltages. It belongs to the amplifier IC hierarchy and supports common functions such as voltage buffering, signal amplification, active filtering, comparators, and analog signal conditioning. Because the LM358ADG4 contains two independent amplifiers in one package, it can reduce board area in dual-channel control, measurement, or interface circuits. Key features include two amplifier circuits, a 700 kHz gain-bandwidth product, a 0.3 V/µs slew rate, and a maximum specified supply voltage of 16 V. The 2 mV input offset voltage is suitable for general signal conditioning, although it is substantially less precise than the offset characteristics expected from dedicated precision amplifiers. Its SOIC-8 surface-mount package supports automated assembly and compact industrial, consumer, and instrumentation designs. The LM358 family architecture combines two general-purpose amplifiers with a single 8-pin package. Its bandwidth supports low-frequency amplification, buffering, filtering, and threshold-detection functions, while the 0.3 V/µs slew rate limits how quickly the output can follow larger input-driven voltage changes. Designers should account for that limitation in pulse, waveform, or feedback applications and keep operating points within the manufacturer’s electrical limits. Typical applications include sensor-signal conditioning, low-frequency active filters, industrial control interfaces, audio preamplifier stages, transducer amplifiers, and dual-channel threshold detection. Two amplifiers in one package are especially useful when a design needs matched circuit topology in two channels, provided both sections operate within compatible common-mode and output-swing conditions. For new layouts, follow the manufacturer’s pin-assignment and application guidance exactly, including bypass placement around the power supply. Keep feedback paths short, route sensitive input and output traces away from switching nodes, and verify stability with the actual source impedance, load, and compensation network. The SOIC-8 footprint also requires attention to thermal dissipation when either amplifier operates continuously near its output-current limit. This product page combines the verified LM358ADG4 specifications, package information, practical application guidance, comparison parameters, and confirmed pin-compatible alternatives. It is intended to help engineers evaluate whether this general-purpose dual operational amplifier fits a board-level signal-conditioning requirement before completing laboratory validation.

LM358ADR2G - Dual 1MHz Op Amp, 3-32V | onsemi | SOIC-8

The onsemi LM358ADR2G is a dual general-purpose operational amplifier with two independent amplifiers, a 1 MHz gain-bandwidth product, and 3 V to 32 V supply operation in an 8-pin SOIC package. It supports single-supply or split-supply operation and accommodates input common-mode voltages that extend to ground or VEE, making it useful in industrial signal-conditioning circuits. An operational amplifier is a voltage-gain device used to amplify weak sensor signals, buffer inputs, implement active filters, compare voltages, and drive analog circuits. The LM358 belongs to the general-purpose operational-amplifier hierarchy, combining two amplifier channels in one package. Its ground-referenced common-mode capability is especially valuable in single-supply systems, where input signals often remain near the lower supply rail. Key characteristics include a 1 MHz gain-bandwidth product, 0.6 V/µs slew rate, low power consumption, and common-mode input range extending to ground or VEE. The dual configuration reduces board area and package count when two amplifier channels are required. Commercial-temperature operation and surface-mount packaging make the device suitable for conventional industrial and commercial equipment rather than only low-volume prototyping. The LM358 series uses established general-purpose amplifier circuitry and is equivalent to one half of an LM324, as described by onsemi. It can operate from a single positive supply or from split bipolar rails, providing flexibility across instrumentation, control, and interface designs. Its 1 MHz bandwidth is sufficient for general-purpose audio, sensor, and feedback-loop applications, although it is not intended for precision or high-speed signal-path work. Typical uses include low-level sensor amplification, current-loop interfaces, differential voltage measurement, active filtering, threshold detection, and general feedback control. The device is especially appropriate when the signal can approach ground and the system cannot accommodate a rail-to-rail input stage. Because the common-mode range extends to ground or VEE, the amplifier can process signals near the negative rail without requiring a separate mid-supply bias. When laying out a circuit, place input and feedback components close to the corresponding amplifier pins and maintain short, low-noise routes around high-impedance inputs. Avoid long PCB traces between the source and noninverting input, particularly when sensing microvolt-level signals. Decoupling capacitors should connect to the supply and ground pins with minimal loop area to limit supply-noise coupling into the amplifier. This product reference combines manufacturer-family characteristics with practical pinout, application, and drop-in replacement guidance. It is structured to help engineers identify the correct onsemi ordering code, understand the 8-pin SOIC footprint, compare pin-compatible devices, and move from device selection into PCB-level implementation without relying on generic LM358 guidance.

LM358ADRE4

LM358ADRE4 - Dual 700 kHz Op Amp in 8-SOIC | Texas Instruments

The Texas Instruments LM358ADRE4 is a dual general-purpose operational amplifier with two amplifier circuits, a 700 kHz gain-bandwidth product, and an operating supply range of up to ±16 V, or 32 V total, in an 8-pin SOIC package. The LM358ADRE4 is supplied in tape-and-reel packaging for automated surface-mount assembly. An operational amplifier is a voltage-feedback amplifier that uses high open-loop gain to amplify the difference between its inverting and non-inverting inputs. Negative feedback defines the closed-loop gain and bandwidth, allowing one amplifier section to perform sensing, buffering, amplification, filtering, or signal-conditioning functions. A dual operational amplifier combines two amplifier channels in one package, reducing board area and simplifying power distribution in analog front ends. The LM358 family is widely used for general-purpose analog signal conditioning because each channel combines a 700 kHz gain-bandwidth product with single-supply or split-supply operation. The 8-SOIC arrangement provides separate inputs and outputs for both channels, along with common power and ground pins. This makes the LM358ADRE4 appropriate for industrial control, sensor interfaces, audio paths, and low-to-moderate-frequency conditioning circuits. The two independent channels can be configured as inverting amplifiers, non-inverting amplifiers, comparators, buffers, or transimpedance stages when suitable feedback and biasing networks are used. Designers should select resistor and capacitor values to meet the required signal bandwidth, gain, input impedance, output loading, and stability objectives. The device is a general-purpose solution rather than a rail-to-rail precision amplifier, so input common-mode range, output swing, offset voltage, and noise should be checked against the actual supply and signal levels. Typical applications include conditioning outputs from resistive sensors, buffering analog-to-digital converter inputs, amplifying low-level audio signals, and implementing active filters. In each case, maintaining adequate supply headroom and checking output-drive capability are important because the input and output operating ranges are not identical to the total supply rating. A practical PCB layout should place input, output, feedback, and compensation components close to the associated amplifier pins. Decoupling capacitors should be connected directly between the supply and ground pins, while long analog traces should be kept away from switching nodes and high-current return paths. The SOIC package is suitable for conventional reflow assembly and automated inspection. This product reference combines the exact ordering information for LM358ADRE4 with practical guidance on amplifier configuration, application fit, PCB implementation, and drop-in comparison. It also highlights which technical details should be confirmed in the manufacturer datasheet before release to production.

The Texas Instruments LM358ADRG4 is a general-purpose dual operational amplifier containing two independent, high-gain, frequency-compensated amplifiers, with a gain-bandwidth product of 700 kHz and slew rate of 0.3 V/us in an 8-pin SOIC package. The device operates from a single supply or split supply and supports an operating voltage range of ±1.5 V to ±16 V. Its two independent channels make it suitable for dual-signal conditioning, buffered sensing, and general analog amplification. An operational amplifier is an analog integrated circuit that uses high open-loop gain and negative feedback to amplify the difference between two input voltages. The LM358 belongs to the operational-amplifier hierarchy within analog signal-chain ICs and power-management applications. Frequency compensation allows each channel to provide stable closed-loop operation in common noninverting, inverting, voltage-follower, summing, and comparator configurations without external compensation networks. The LM358ADRG4 provides two amplifier sections in one compact 8-SOIC package, reducing board area compared with separate single-channel amplifiers. Its 700 kHz gain-bandwidth product supports moderate-bandwidth signal paths, while the 0.3 V/us slew rate limits large-signal response speed. The wide ±1.5 V to ±16 V operating range accommodates both low-voltage and conventional bipolar analog systems, and the split-supply capability allows operation around a nonzero midpoint voltage. Each amplifier channel includes differential inputs, an output, and independent biasing. Internal compensation is a key practical feature because it eliminates the external frequency-compensation capacitor commonly associated with general-purpose op-amp designs. However, stable operation still depends on correct feedback routing, suitable output loading, and appropriate input and output voltage ranges. The device is intended for linear amplification rather than high-speed, low-voltage, or rail-to-rail precision applications. Typical uses include sensor-signal conditioning, audio preamplification, motor and actuator control loops, active filtering, low-current buffer stages, and general dual-channel instrumentation. The two channels can amplify related signals or perform separate functions, such as sensing and reference buffering, while keeping the implementation in one standard surface-mount package. For PCB design, place input and output connections away from high-current switching paths, maintain short feedback traces, and use a local bypass capacitor from the supply pin to ground. Check input common-mode and output-swing limits against the actual single- or split-supply rails. Avoid relying on the LM358 for millivolt-level precision because its input offset and bias characteristics are appropriate for general-purpose rather than precision instrumentation. This page combines device specifications, application guidance, drop-in replacement comparisons, and design notes to support faster engineering selection.

LM358AM - Dual 8-SOIC Operational Amplifier | Texas Instruments

The Texas Instruments LM358AM is a dual general-purpose operational amplifier with two independent, internally frequency-compensated amplifier channels in an 8-pin SOIC package. The device is designed for operation from a single power supply over a wide voltage range, providing a practical solution where two amplified signals must be processed by one compact analog IC. The verified product information identifies the LM358AM as a standard, general-purpose, two-circuit amplifier and describes its low-power consumption, high gain, and wide operating-voltage capability. An operational amplifier, or op-amp, is a voltage-controlled differential amplifier whose closed-loop behavior is determined mainly by external feedback components. The LM358 belongs to the broad hierarchy of operational amplifiers, analog amplifiers, analog signal-conditioning ICs, and semiconductor devices. Its two internally compensated channels can perform common tasks such as voltage amplification, buffering, summing, comparisons, active filtering, and feedback control when configured with suitable external resistors and capacitors. The principal advantages of choosing a dual amplifier are functional integration and reduced board area. Two independent amplifiers in one LM358AM package can replace two separate single-channel devices while preserving the familiar SOIC-8 footprint. The manufacturer describes the series as suitable for general-purpose applications and emphasizes its combination of low power consumption, high gain, and a wide supply-voltage range. Exact voltage, current, gain-bandwidth, input-offset, and temperature limits require confirmation from the full manufacturer datasheet because those values were not included in the supplied web records. The architecture is based on two independent, high-gain, internally frequency-compensated operational amplifiers. Internal frequency compensation avoids the need for an external compensation capacitor in ordinary closed-loop configurations, simplifying amplifier selection and PCB design. Because the channels are independent, one can amplify a sensor signal while the other performs a different function, such as comparison, current-to-voltage conversion, active filtering, or an output driver. Typical uses include industrial sensor conditioning, low-cost control loops, audio preamplification, current sensing, comparator-style threshold detection, and general analog signal processing. Single-supply operation is particularly useful in embedded equipment because the amplifier can operate from a positive rail and ground. Designers must still check input and output common-mode limits, output-swing behavior, load capability, and stability for the intended configuration before releasing production hardware. PCB implementation should preserve the exact pin assignment of the chosen SOIC-8 manufacturer variant and provide a solid ground return. Decoupling capacitors should be placed close to the supply pins, while feedback resistors and compensation networks should be kept short to minimize noise pickup and parasitic instability. The LM358AM is not rail-to-rail by implication alone; input and output behavior must be verified against the relevant datasheet limits. This product record combines verified distributor and manufacturer references, package information, commercial availability links, and practical selection guidance. It also separates documented facts from missing numeric parameters so engineers can cross-check voltage limits, pricing, compliance, and production details against the authoritative LM358 datasheet before design release.

Texas Instruments LM358AM/NOPB is a low-power, dual operational amplifier in an 8-pin SOIC package. The device contains two independent amplifiers, operates from a 3 V to 32 V single supply, and provides a 700 kHz gain-bandwidth product with 0.3 V/us slew rate. Its input common-mode range extends toward the supply rails, making it suitable for low-voltage signal conditioning, buffering, and general-purpose analog control. An operational amplifier is a voltage-controlled differential amplifier that uses feedback to create stable, programmable gain. The LM358 belongs to the general-purpose operational-amplifier family within the broader analog IC and semiconductor hierarchy. Unlike precision or rail-to-rail designs, the LM358 is primarily intended for economical systems that operate from single or dual supplies and need moderate bandwidth, input common-mode range, and output-current capability. The two amplifier sections are electrically independent, allowing each channel to process a different signal within the same package. Key features include a 700 kHz gain-bandwidth product, 0.3 V/us slew rate, low-power operation, and an output-current capability cited as 20 mA. These characteristics support common tasks such as sensor amplification, error amplification, voltage comparison, active filtering, and signal buffering without requiring two separate amplifier packages. The LM358AM/NOPB is specified for a 3 V to 32 V supply range and an input common-mode range of ±1.5 V to ±16 V, depending on the operating configuration. Because it is not rail-to-rail, output swing and input range depend on the selected supply voltage and common-mode headroom. Designers should preserve those margins when processing signals close to the positive or negative rail. Typical uses include 5 V sensor interfaces, industrial control loops, audio preamplifier stages, battery-powered instrumentation, active filters, and comparator-style feedback networks. The 8-pin SOIC package is easy to assemble on conventional through-hole-compatible PCB land patterns and supports automated manufacturing. The two-amplifier configuration can also reduce board area when two independent analog channels are required. Design consideration: keep feedback networks close to the amplifier pins, provide stable bypass capacitance on the supply rail, and avoid forcing either input beyond the specified common-mode range. Output current and total power dissipation must be checked against the actual load, supply voltage, and ambient temperature because the two channels can contribute independently to device heating.

The Texas Instruments LM358AMX/NOPB is a dual general-purpose operational amplifier with two independent amplifier circuits, a 32 V maximum supply rating, 1 MHz gain-bandwidth product, and an 8-pin SOIC package. The manufacturer specifies a 0°C to 70°C operating-temperature range for this ordering variant, making it appropriate for commercial and industrial equipment that does not require an extended-temperature grade. An operational amplifier is an analog integrated circuit that uses high-gain differential amplification to compare an inverting input with a non-inverting input. The LM358 family belongs to the broader hierarchy of operational amplifiers, analog amplifiers, and semiconductor signal-conditioning devices. Two amplifiers in one package can provide gain, buffering, active filtering, current-to-voltage conversion, or general feedback control when their power requirements and electrical limits suit the circuit. The LM358AMX/NOPB combines two general-purpose amplifier sections with a 32 V supply capability and 1 MHz bandwidth. Its dual-circuit configuration saves board area compared with two separate single amplifiers, while the SOIC (D) package supports conventional surface-mount assembly. The 0°C to 70°C rating is the principal distinction to verify when replacing this part in equipment exposed to temperatures outside the commercial range. Each amplifier section operates from the same external supply pins, and the package provides separate input and output connections for both channels. The manufacturer identifies the device as a standard general-purpose amplifier rather than a precision, low-noise, high-speed, or rail-to-rail-input part. Designers should therefore base input-signal range, offset, bias-current, slew-rate, and output-swing decisions on the corresponding LM358-N electrical characteristics rather than assume the behavior of newer amplifier families. Typical uses include two-channel sensor conditioning, buffered analog measurements, audio preamplification, active filters, comparator-style threshold circuits, and general industrial control. A single package is especially useful when two modest-bandwidth signal channels share the same board and supply rails. Independent amplifier channels also allow one section to perform signal conditioning while the other handles monitoring or feedback within the same system. For PCB design, use the manufacturer's pin-description table when assigning tracks because exposed-pad, thermal, and no-connect details depend on the exact package drawing. Place the input network close to the corresponding amplifier pins, keep feedback-loop routing compact, and provide adequate decoupling between the supply pins and ground. Confirm output swing and common-mode limits at the selected supply voltage before using the device near either rail. This product page combines the manufacturer's exact ordering information with practical guidance on package reuse, dual-amplifier implementation, thermal-range verification, and same-footprint sourcing. It helps engineers distinguish the 32 V, 1 MHz commercial-temperature device from parts with different pinouts, package styles, extended-temperature ratings, or substantially different amplifier performance.

LM358AN

LM358AN - Dual 1MHz Op Amp, 3-36V Single Supply | Texas Instruments

The Texas Instruments LM358AN is a dual, general-purpose operational amplifier providing two independent channels in an 8-pin PDIP (through-hole) package, with an A suffix indicating the lead-free (RoHS-compliant) finish. Each channel offers a 1.0 MHz unity-gain bandwidth, 0.3 V/us slew rate, and operation from a single 3 V to 36 V supply, making it the standard dual single-supply op amp for cost-sensitive analog signal conditioning. An operational amplifier is an analog building block that amplifies the voltage difference between its two inputs. The LM358 belongs to the single-supply, rail-to-rail-input-capable general-purpose family: it is designed to run from one positive rail and a ground reference, so its input common-mode range extends from 0 V up to roughly 1.5 V below the positive supply. This topology sits at the bottom of the hierarchy of integrated circuit amplifiers: operational amplifier -> voltage-feedback amplifier -> amplifier IC -> analog semiconductor. Key features include differential input stage trimming for low offset, internal frequency compensation so no external nulling or compensation components are required, and output-stage design that sources up to 40 mA and sinks up to 20 mA while staying within a few tens of millivolts of the supply rails. The two amplifiers are independent, allowing them to be used in separate signal chains or in differential and instrumentation configurations within a single package. Technically, the LM358 uses a class-B output stage, so crossover distortion around 0 V output is a consideration in precision AC applications. The open-loop gain is typically 100 dB with a unity-gain bandwidth of 1 MHz, so closed-loop stability depends on keeping the feedback network noise-gain flat across the frequency range. Input bias current of roughly 20 nA and input offset voltage of a few millivolts make it appropriate for impedance levels above about 100 kOhm. Typical applications include DC amplifier stages in sensor front ends, low-side current sensing with a shunt, active filters, comparators with reference inputs, audio mixers, and general instrumentation in industrial control and consumer equipment. The DIP-8 package is favored for through-hole assembly, prototype boards, and legacy repair where a surface-mount footprint would be impractical. When designing with the LM358AN, keep input and output signals within the input common-mode range, and remember that at supply voltages below about 5 V the output swing limitations consume a larger share of the rail-to-rail span. For low-offset or low-noise instrumentation, add an external offset trim or select a higher-grade precision amplifier instead. This page consolidates distributor availability, drop-in replacement options, and application-specific design guidance for the LM358AN into a single engineering reference that goes beyond a manufacturer datasheet.

LM358AN/NOPB - Dual 32 V Op Amp | Texas Instruments

The Texas Instruments LM358AN/NOPB is a dual operational amplifier containing two independent, high-gain, internally frequency-compensated amplifiers in an 8-pin PDIP package. The device supports operation from a single supply across a wide voltage range, with the LM358 family identified for operation up to 32 V and a gain-bandwidth product of 1 MHz. The LM358AN/NOPB designation identifies the PDIP package version associated with the Texas Instruments LM358 family. An operational amplifier is an analog signal-processing IC that uses differential input voltage to control an output voltage. A dual device contains two amplifiers that operate independently but share a supply. The LM358 belongs to the general-purpose operational-amplifier hierarchy, where its differential input stage, high open-loop gain, internal frequency compensation, and wide supply range make it suitable for signal conditioning, amplification, filtering, and control applications that do not require rail-to-rail input or output operation. The principal family-level characteristics include two amplifier circuits, a maximum supply rating of 32 V, a 1 MHz gain-bandwidth product, approximately 700 kHz bandwidth for the LM358AN comparison entry, and a slew rate of 0.3 V/us. Each amplifier has two differential inputs and one output. Internal frequency compensation removes the need for an external compensation network in many conventional closed-loop configurations. The wide operating supply permits use in both low-voltage 5 V systems and higher-voltage industrial control circuits. The two amplifiers share power-supply connections but retain separate input and output pins, allowing one section to perform sensing or amplification while the other performs buffering, level conversion, or an additional control function. Because the device is intended for single-supply operation, its common-mode input range and output swing are important design constraints. Engineers should verify those limits against the exact operating condition required by the application rather than assuming behavior from a rail-to-rail amplifier. Typical uses include transducer-signal conditioning, low-frequency active filters, comparators with an external reference, loop-error amplifiers, audio preamplification, and general-purpose analog control. The dual configuration is especially useful when a board needs two independent analog channels without allocating space for two separate amplifier packages. The internal compensation also simplifies designs requiring stable gain, although stability still depends on the selected feedback network, output loading, and signal frequency. A primary design consideration is input and output range. On a single 5 V supply, the LM358 does not necessarily swing rail to rail, so the signal and feedback network must remain inside its common-mode and output-swing limits. Decoupling capacitors should be placed close to the supply pins, and unused amplifier sections should be configured conservatively rather than left floating. Input-referred offset and bias current should also be checked against the source impedance and required measurement accuracy. This product page combines the exact LM358AN/NOPB ordering identity, manufacturer family specifications, package details, sourcing guidance, and engineering-focused application analysis. It also organizes same-footprint alternatives, comparison parameters, and practical design notes so engineers can assess fit before committing to a PCB and production BOM.

LM358AP - Dual 30V 700kHz Op Amp | Texas Instruments

Texas Instruments LM358AP is a dual general-purpose operational amplifier with two independent amplifiers, a 30 V maximum supply rating, 700 kHz gain-bandwidth product, and an 8-pin PDIP package. It operates from 3 V to 30 V, supports input and output common-mode ranges suitable for single-supply signal conditioning, and is specified for 0°C to 70°C operation. An operational amplifier, or op amp, is an analog integrated circuit that amplifies the voltage difference between its two inputs while using negative feedback to perform a defined gain function. The LM358 belongs to the dual operational amplifier, voltage-feedback amplifier, analog IC, and semiconductor hierarchy. Its two internally compensated channels make it suitable for sensor interfaces, transducer amplifiers, buffer stages, and general-purpose analog control circuits without requiring a separate single amplifier package. The principal performance figures are a 700 kHz gain-bandwidth product, 0.3 V/µs slew rate, and approximately 2 mV input offset voltage. These characteristics make the LM358AP suitable for low-to-moderate frequency precision analog circuits. Its dual configuration provides channel-to-channel integration, while the wide 3 V to 30 V supply range allows operation from a single low-voltage rail or from split supplies. The device is available in an 8-pin PDIP package for through-hole PCB assembly. Each channel uses a differential input stage, voltage-gain stage, and output stage, with internal compensation providing stable operation without an external compensation capacitor. Although the device is commonly associated with single-supply operation, its common-mode input range does not extend all the way to the positive supply rail. Designers should therefore verify the signal excursion against the common-mode limits before using the amplifier directly at the top of a low-voltage supply. Typical uses include low-current sensor conditioning, buffered control inputs, audio preamplifier stages, active filtering, and general-purpose instrumentation. In a sensor interface, the LM358AP can amplify a small transducer signal while its dual channels support a second stage such as an inverter, buffer, or active filter. The 700 kHz bandwidth provides ample margin for slow sensor signals and low-frequency control loops. PCB layout should keep input traces short, place bypass capacitance near the supply pin, and route output returns independently from sensitive input paths. Although the PDIP package is through-hole and easy to prototype, its lead pitch requires adequate clearance from adjacent components. Input and output nodes should also be kept apart to reduce parasitic feedback and oscillation risk. This product page combines the LM358AP electrical characteristics, package details, application guidance, compatible replacements, and practical PCB considerations in a format that helps engineers evaluate the device before committing a through-hole design to production.
