LM2904TH-13

LM2904TH-13 - Dual 700 kHz Op Amp | Diodes Incorporated

Diodes Incorporated LM2904TH-13 is a dual general-purpose operational amplifier in an 8-pin TSSOP package. The device contains two independent high-gain amplifiers, supports a 700 kHz bandwidth, and is designed for operation from a single supply or from split supplies. The LM2904 family provides a practical choice for signal conditioning, feedback control, and analog circuit designs requiring two amplifiers in one package. An operational amplifier, commonly called an op amp, is a high-gain DC-coupled analog amplifier whose behavior is controlled by feedback around the device. The LM2904 combines two independent amplifier channels in one package, reducing board area compared with two separate single-amplifier devices. Its 8-pin TSSOP package supports compact surface-mount assemblies and exposes supply, input, and output connections for each channel. The most prominent specified characteristics are the two-amplifier configuration, 700 kHz bandwidth, and supply capability extending to ±18 V, equivalent to a 36 V total span. The device is categorized as a standard general-purpose amplifier and is designed for both single-power-supply and split-supply operation. Its architecture also targets low input-offset voltage, making it relevant to closed-loop amplifier and comparator-style signal-processing applications when configured appropriately. The LM2904 series combines independent high-gain operational amplifiers with a broad supply-voltage range. Because the two channels are independent, one channel can process a sensor signal while the other performs an active filter, level conversion, or feedback function. Common-mode and output-voltage limitations still depend on the selected supply voltages, so every analog signal path must remain inside the amplifier’s valid input and output ranges. Typical uses include low-frequency instrumentation, buffered sensor interfaces, audio preamplification, analog gain stages, and dual-axis control loops. The 700 kHz bandwidth is most appropriate for general-purpose signal paths rather than high-speed video, RF, or precision data-conversion applications. Split-supply operation can simplify bipolar signal handling, while single-supply operation may require input and output biasing around the midpoint of the supply. Designers should use the manufacturer’s pin-description and typical-application information to establish channel assignments, bypass-capacitor placement, and acceptable output-load conditions. Decouple each supply rail close to the device, keep feedback paths short, and verify that input common-mode voltage and output swing remain valid over the full supply range and temperature range intended for the design. This page organizes the key device characteristics, practical application guidance, verified pricing references, pin-location information, and same-footprint replacement options. It also distinguishes documented LM2904 family choices from alternatives that would require a different package or different electrical capabilities, helping engineers narrow a redesign without overlooking PCB compatibility.

The onsemi LM2904VDMR2 is a dual general-purpose operational amplifier with a 3 V to 32 V supply range, 1 MHz gain-bandwidth product, and 8-MSOP package. Designed for low power consumption, the device accepts single-supply or split-supply operation, while its common-mode input voltage range can extend to ground or VEE. It is suited to industrial signal-conditioning, transducer, and analog-control systems. An operational amplifier is a voltage-gain building block used to amplify small signals, buffer sensors, compare voltages, and implement active analog filters. The dual LM2904 family combines two amplifiers in one package, reducing board area compared with separate single amplifiers. Its ability to operate from a single positive supply or from split positive and negative rails gives it broad utility in both grounded-signal systems and bipolar analog environments. Key features include low power drain, a 1 MHz gain-bandwidth product, and a common-mode input range that extends to ground or VEE. The 3 V to 32 V operating range supports both conventional 5 V and 24 V industrial systems when the total supply remains within the rated range. The 8-MSOP surface-mount package also supports compact, high-density analog boards while providing adequate lead spacing for automated assembly and inspection. The LM2904 architecture derives from the circuit design used in onsemi's quad operational-amplifier family. It is intended for general-purpose applications where low power consumption and flexible supply configurations are more important than precision, rail-to-rail input/output performance, or the bandwidth of modern CMOS amplifiers. Because the input common-mode range can reach ground or VEE, the device can process signals near the lower supply rail when correctly biased. Typical applications include 0–5 V or 0–10 V industrial sensor interfaces, low-level transducer amplification, analog alarm and threshold circuits, active low-pass filters, and general control-signal conditioning. It may also be used in battery-powered instrumentation where the selected operating point must balance signal bandwidth against power drain. Split-supply operation is useful for bipolar sensor signals or analog stages that require both positive and negative swing around ground. When designing around the LM2904VDMR2, verify input and output voltage limits at the selected supply voltage and load. Input and output decoupling should be placed close to the device, and unused amplifier channels must be configured according to the manufacturer’s recommended stable operating conditions. Avoid relying on rail-to-rail behavior, and account for input offset and bias-current errors when designing high-accuracy signal chains. This product page consolidates the confirmed supply, bandwidth, package, and application characteristics with drop-in replacement analysis, package comparison, and practical circuit guidance. It helps engineers distinguish genuine footprint-compatible options from amplifiers that are only functionally similar before committing a new board revision.

Its common-mode input range extends to ground or VEE, allowing useful operation in single-supply circuits where the input signal approaches the negative supply rail. Key features include two amplifier circuits per package, a 1 MHz gain-bandwidth product, a 0.6 V/µs slew rate, and a specified operating voltage range of up to ±16 V, equivalent to 32 V across the supply rails. The low-power design supports both single-supply and split-supply operation. The standard 8-SOIC package also simplifies assembly in designs that do not require a high-performance precision amplifier. The LM2904 architecture is intended for general-purpose amplification rather than rail-to-rail input or output operation. Its common-mode input behavior reaches ground or VEE, making it particularly useful for circuits powered from a positive rail and ground. As with any feedback amplifier, stable operation depends on suitable compensation, output loading, source impedance, and the selected gain network. Typical uses include buffering sensor outputs, amplifying low-level analog signals, conditioning potentiometer inputs, driving moderate loads, building active filters, and providing general-purpose gain stages in industrial or embedded systems. Two amplifiers in one SOIC package can also simplify layouts where matched general-purpose stages are needed. When designing around the LM2904, check the common-mode input range and output swing at the intended load rather than assuming rail-to-rail behavior. Place input and feedback components close to the device, provide adequate bypassing near the supply pins, and verify stability at the lowest planned gain. The manufacturer datasheet should guide compensation, load capability, and absolute maximum ratings. This product page combines the exact LM2904VDR2G package and electrical identity with practical design guidance, pin-level information, verified source links, and a package-matched replacement comparison. These engineering details help buyers distinguish the dual general-purpose amplifier from single-amplifier, automotive-qualified, and other LM-family variants before committing to a PCB design.

Low supply current and ESD protection are additional features identified in the family datasheet. The amplifier family is designed for general-purpose operation rather than high-speed precision signal paths. Its 700 kHz bandwidth is suitable for moderate-frequency conditioning, while the automotive qualification and wide supply operating range suit electronic control units, sensor interfaces, actuator drivers, battery-powered systems, and industrial measurement modules. Users should confirm output-swing, input-common-mode, offset, and stability limits against the specific operating conditions in the manufacturer datasheet before finalizing a design. Typical applications include low-side current sensing in automotive electronic control units, conditioning resistive sensor signals, amplifying sensor and transducer outputs, active filtering, and general voltage amplification. The two amplifier sections can process related signal paths while sharing one supply package, which simplifies power distribution and reduces component count compared with two discrete single amplifiers. PCB design should provide a stable ground reference, short feedback paths, appropriate input-biasing, and decoupling close to the supply pins. Because automotive environments can contain electrical transients and ESD events, system-level protection and validation remain essential even though the amplifier family includes ESD-protection features.

LM2924M

LM2924M Low-Power Op Amp/Comparator | Texas Instruments

Texas Instruments LM2924M is a low-power dual-purpose analog IC containing two independent building blocks: a high-gain, internally frequency-compensated operational amplifier and a precision voltage comparator. The device is packaged in an 8-pin SOIC and is identified as an industrial-temperature-grade component. This combination allows one package to provide signal amplification and threshold detection without using separate amplifier and comparator packages. An operational amplifier is a voltage amplifier whose closed-loop gain is established by an external feedback network. A voltage comparator compares two input voltages and switches its output according to their relationship. The LM2924M combines these complementary functions in a single analog device, placing it in the operational-amplifier and comparator hierarchy while supporting transducer, sensing, control, and signal-conditioning applications. The internally frequency-compensated operational amplifier is designed to operate without an external compensation capacitor, simplifying implementation in basic gain configurations. Its comparator section provides an independent decision-making channel, allowing the two internal circuits to monitor or condition separate signals simultaneously. Because the amplifier and comparator are independent building blocks, their inputs and outputs can be used for different stages of a system. The National Semiconductor datasheet describes the LM2924M as a low-power operational amplifier and voltage comparator for precision voltage-amplification and related analog signal-processing needs. The 8-pin SOIC package provides a compact surface-mount format for industrial equipment, embedded controls, instrumentation interfaces, and mixed analog-digital circuit boards. Typical applications include transducers whose weak outputs require voltage amplification, sensor interfaces requiring a defined switching threshold, industrial control loops, and analog monitoring subsystems. The dual internal architecture can reduce board area when a design needs both continuous analog amplification and discrete threshold detection. For PCB implementation, assign the supply, ground, input, and output pins according to the manufacturer pin-description table and preserve the recommended input/output operating conditions. Confirm signal ranges, output states, stability requirements, and temperature limits against the device datasheet before connecting external transducers or logic interfaces.

LM2924MX

LM2924MX - Low-Power Amplifier/Comparator | Texas Instruments

Texas Instruments LM2924MX is a low-power bipolar analog IC that combines an operational-amplifier function with voltage-comparator operation in an 8-pin SOIC package. It is identified as a single-function transducer-amplifier circuit, is designed for industrial-temperature use, and is supplied in a rectangular surface-mount SOP package. The LM2924MX therefore serves as a compact analog signal-conditioning component for systems that require amplification and threshold detection in one package. An operational amplifier is a voltage-controlled analog amplifier whose open-loop gain is made large enough to amplify small signals accurately when negative feedback is applied. A voltage comparator compares one input voltage with another and changes its output state when a threshold is crossed. Together, these functions form part of the broader linear and mixed-signal IC hierarchy, where they support sensor conditioning, control loops, signal detection, and industrial interface circuits. The LM2924MX combines three notable product attributes. First, its bipolar construction places it in the classical family of analog amplifier ICs. Second, its single-function analog-circuit architecture supports compact implementation of transducer and signal-conditioning paths. Third, the 8-pin surface-mount SOIC package permits automated assembly while reducing board area compared with larger through-hole packages. Its industrial temperature grade also positions it for equipment operating beyond typical commercial-temperature conditions. LM2924MX is identified as a low-power operational amplifier and voltage comparator. This dual operating role allows the same device to amplify a low-level analog signal and evaluate whether that signal has crossed a defined reference level. In feedback-based configurations, the amplifier behavior supports closed-loop gain; in open-loop threshold service, the comparator behavior provides a digital indication of an analog condition. Exact gain-bandwidth, input-offset, supply-voltage, and output-current limits should be confirmed from the manufacturer datasheet before final circuit sizing. Typical uses include bridge or resistive-transducer signal conditioning, industrial sensor interfaces, low-level control-signal amplification, threshold detection, and alarm-generation circuits. The 8-pin SOIC footprint is suitable for compact analog boards where a surface-mount part is preferred and where signal conditioning must be placed close to the sensor or source to minimize susceptibility to interference. Designers should determine the allowable supply range, input common-mode range, output swing, input-offset voltage, noise, and comparator propagation behavior from the manufacturer datasheet. Decoupling capacitors should be placed close to the supply pins, while sensitive input routing should avoid switching nodes and high-current return paths. Feedback resistors and any hysteresis network must be evaluated for the required gain, offset, and threshold stability. This product page consolidates the exact package, temperature-grade, circuit-type, and lifecycle information for LM2924MX, maps suitable analog applications, and provides engineering guidance for layout, compensation, and sourcing. It also distinguishes confirmed drop-in replacements from merely similar amplifier or comparator families so that PCB reuse decisions remain technically defensible.

LM293AD

LM293AD - Dual Differential Comparator, 2-36V | Texas Instruments

Texas Instruments LM293AD is an industrial-grade dual differential comparator with two independent comparison channels, a 2 V to 36 V supply range, rail-to-rail input operation, and open-collector/open-drain outputs. The device is packaged in an 8-pin SOIC and is designed for sensing and control applications involving wide input and output voltage conditions. A differential comparator is an integrated circuit that compares two input voltages and changes its output state according to their relationship. Its two channels can monitor thresholds, detect crossings, implement window functions, or generate control signals. The LM293 belongs to the comparator hierarchy within analog interface ICs, where it bridges analog sensing and digital control logic. The LM293AD operates from 2 V to 36 V and provides a response time of approximately 300 ns. Its common-mode input range includes ground, and its differential input range can equal the maximum-rated supply voltage of ±38 V according to the manufacturer product information. Open-collector outputs support wired logic, pull-up arrangements, level translation, and compatibility with TTL, MOS, and CMOS systems. Each comparator section compares an inverting input with a non-inverting input. When the non-inverting input is higher, the corresponding open-collector output transistor turns off; when the inverting input is higher, the output transistor turns on. An external pull-up resistor is required for conventional open-collector operation. The two channels share the supply pins but retain separate input and output pins. Typical uses include industrial sensor interfaces, battery monitoring, power-supply fault detection, overvoltage protection, relay or LED indication, and control systems that compare an analog voltage against a reference. The wide operating supply range is useful when the comparator must tolerate industrial transients while operating from a higher-voltage rail. Designers should verify input and output absolute maximum ratings, provide adequate pull-up resistors, maintain a valid common-mode range, and account for output-current limits when several wired-open-collector outputs share a bus. Because the outputs can sink current but cannot source it independently, external pull-ups determine the high logic voltage and rise-time behavior. This product page combines manufacturer specifications, verified distributor listings, same-package replacement guidance, and practical comparator-design notes. It helps engineers evaluate the LM293AD for industrial threshold detection, protection, monitoring, and open-collector interface designs without confusing it with open-drain parts that use different output structures.

LM293AM - Dual Differential Comparator, 36 V, SOIC-8 | onsemi

The onsemi LM293AM is a dual differential comparator designed for single-supply operation up to 36 V or dual-supply operation up to ±18 V, and it is available in an 8-pin SOIC package. Its differential inputs allow two voltages to be compared, while the open-collector output structure supports flexible interface and pull-up arrangements in control, sensing, and protection circuits. A differential comparator is an analog integrated circuit that compares two input voltages and changes its output state according to their relationship. The dual configuration provides two independent comparators in one package. When used with an external pull-up, an open-collector output can drive TTL, MOS, or CMOS-compatible circuitry while also allowing wired logic, level translation, or system reset behavior. The LM293AM belongs to the comparator hierarchy within amplifier and interface ICs. Key features include single-supply operation to 36 V, dual-supply operation to ±18 V, a typical low-current drain of 800 µA, and a typical input bias current of 25 nA. The device can compare input voltages near ground potential and is compatible with multiple logic families. Its low input bias current helps reduce source-loading effects in high-impedance sensing networks, while the wide supply range supports industrial and automotive-style control environments. The LM293AM uses open-collector outputs rather than push-pull outputs. This architecture provides a useful advantage when a comparator output must remain inactive until an external pull-up supplies the required logic-high voltage. It also supports open-wired signal arrangements, but every application must include the appropriate pull-up resistor and verify that the resulting rise time is acceptable. The operating common-mode range, differential input limits, output sink capability, and timing behavior should be checked against the manufacturer datasheet for the selected manufacturer version. Typical applications include industrial control systems, power-supply supervision, motor and solenoid protection, battery monitoring, sensor-threshold conditioning, window or level detection, and general-purpose logic interfaces. The dual comparator arrangement is particularly useful when one circuit monitors two related thresholds or when an enable function and a fault signal can be implemented with the two channels in a compact footprint. For PCB design, place the device so that sensitive input traces remain away from switching nodes and output pull-up routing. Keep input and output paths separate to reduce feedback through supply or board-level coupling. Confirm the logic-high level, output rise time, input common-mode range, supply decoupling requirements, and operating temperature range before releasing the design for production. This page combines manufacturer-family operating limits, package details, sourcing guidance, replacement analysis, and practical PCB considerations to support faster component selection. Review the complete pin assignment and electrical characteristics in the LM293AM datasheet before layout, particularly when the same circuit must accommodate multiple LM293-family variants.

LM293AN

LM293AN - Dual Open-Collector Comparator | STMicroelectronics

The STMicroelectronics LM293AN is a low-power dual voltage comparator with two independent comparator channels, open-collector and open-drain outputs, and an 8-DIP package. The device is designed for general-purpose signal comparison and can operate from a single supply over a wide voltage range, while split-supply operation is also possible. Its listed rail-to-rail input designation, ground-referenced common-mode capability, and TTL, MOS, and CMOS output compatibility make it suitable for threshold detection, level translation, and analog-control systems. A voltage comparator is an integrated circuit that compares two input voltages and produces a logic-level indication of their relationship. In this role, LM293AN belongs to the comparator IC hierarchy within analog and mixed-signal semiconductors. Each of its two channels can evaluate a non-inverting input against an inverting input, allowing one package to perform two related comparisons while keeping channel operation independent. The LM293 family documentation identifies low power consumption as a defining characteristic and specifies input-offset voltage as low as 2.0 mV maximum for the associated two-comparator family. Open-collector outputs provide flexibility when the destination device requires a pull-up resistor, particularly in wired logic, relay-driver, and legacy digital-interface applications. The outputs are also listed as compatible with TTL, MOS, and CMOS logic families. Operation from a single supply is central to the device design. The common-mode input range includes ground, while the differential input voltage can extend to the maximum-rated supply voltage of ±38 V according to TI's LM293 family information. The 8-DIP mechanical format provides through-hole access to the two comparator channels, power, ground, and output connections. Typical uses include industrial control thresholds, sensor-interface decisions, window comparators, oscillator and timer designs, and general logic level conditioning. The two independent channels can also implement a larger comparator arrangement through external resistor networks. Open-collector outputs make pull-up selection an important part of the interface design because the output cannot directly drive a logic high without this external support. The main design consideration is that open-collector outputs require correctly selected pull-up resistors and adequate logic-level rise time at the driven node. Supply decoupling, input-source impedance, output load, and common-mode headroom should be reviewed against the application's operating conditions. This page consolidates the verified device identity, package information, sourcing links, and practical comparator-selection guidance.

The verified distributor listing identifies it as a standard general-purpose comparator with open-collector, open-drain, rail-to-rail operation in an 8-SOIC package. The device contains two independent comparator channels, making it suitable for threshold detection, level shifting, window monitoring, and basic analog control systems. According to the Texas Instruments LM293 product page, the device is a dual differential comparator in an industrial-grade family; detailed electrical limits are not supplied in the verified excerpts and therefore remain marked for data completion. A comparator is an analog signal-conditioning IC that compares two input voltages and produces a logic-level output indicating which input is higher. A differential comparator belongs to the broader comparator, amplifier, and analog interface hierarchy, while the LM293D is specifically a low-power, dual-channel comparator for embedded and control applications. Its two independent channels allow simultaneous comparison of two signal pairs, provided the device operates within the manufacturer-rated common-mode and supply limits. The verified TI page states that the LM293 family supports wide supply-voltage operation, including systems using split power supplies. TI also states that the B-version is a drop-in replacement for LM293, LM393, and LM2903; however, the provided data does not establish that every related suffix is electrically identical for every use condition. The LM293D listing identifies open-collector/open-drain and rail-to-Rail output characteristics, which are important when interfacing with pull-up-based digital systems. Typical uses include monitoring a battery or power rail, detecting sensor thresholds, comparing external reference voltages, and implementing basic overvoltage or undervoltage indication. The open-drain output requires an external pull-up resistor when the output must rise to a defined logic level. Because the verified data does not provide exact input-offset, response-time, supply-current, or temperature values, those specifications are retained as data-needed markers rather than inferred from related devices. For PCB design, place the IC close to the compared signals and use short, low-noise routing for high-impedance input nodes. Keep pull-up resistors close to open-drain outputs, and account for input common-mode range and supply polarity in both single-supply and split-supply systems.

LM293DG

LM293DG - Dual Precision Comparator, 2-36V, SOIC-8 | onsemi

The onsemi LM293DG is a dual independent precision voltage comparator in an 8-pin SOIC package, built for single or split supply operation across a 2 V to 36 V supply range. Each channel offers an input offset voltage as low as 2.0 mV, a 1.3 microsecond response time, and a supply current of about 400 microamps per channel, with an open-collector (open-drain) output stage compatible with TTL, MOS and CMOS logic. A comparator is a differential amplifier used as a simple decision element: it compares two input voltages and switches its output state when the non-inverting input rises above the inverting input. The comparator category sits above discrete transistor switches in the signal-conditioning hierarchy and below instrumentation amplifiers in the analog IC family, sitting in the amplifier IC / signal conditioning control group of parts such as op amps, references and sensor interface ICs. The LM293 series is distinguished from general-purpose comparators by its low input offset voltage, wide supply range and ability to operate with the common-mode input range extending to ground, which makes it a strong fit for single 5 V or single 12 V systems where the signal of interest lives near the negative rail. The two channels are fully independent, each with its own pair of inputs and output. The open-collector output stage is the key architectural feature: the output transistor sinks current but never sources it, so an external pull-up resistor to the supply or logic rail is required to establish a valid high level. That architecture permits level shifting to any voltage up to the maximum supply, wired-AND bus tying, and direct drive of relay or solenoid drivers without a buffer stage. Because the output stage is a bipolar NPN transistor, output sink current is limited compared with modern CMOS comparators. Typical applications include overvoltage and undervoltage protection in linear and switching power supplies, battery and pack monitoring window comparators, motor stall and over-current detection, industrial sensor thresholding, and automotive-style sensor protection. The SOIC-8 package with 1.27 mm lead pitch supports both through-hole assembly and standard surface mount reflow, and the -25 C to +85 C ambient range covers industrial and consumer equipment. When designing with the LM293DG, always fit a pull-up resistor on each output and check the sink current against the pull-up value and the load. If your design needs rail-to-rail input operation, push-pull outputs, or a supply below 2 V, a CMOS comparator is the better choice; if it needs low offset with wide supply and open-drain flexibility, the LM293DG remains a proven, low-cost choice. This page consolidates manufacturer specifications, drop-in replacement candidates, pin-level detail and practical design guidance so that you can qualify the LM293DG for an existing board revision without redrawing the footprint.

According to the STMicroelectronics LM293N product description, it is designed for single-supply operation across a wide voltage range, while operation from split power supplies is also possible. The verified distributor listing identifies the device as an 8-DIP comparator with open-collector/open-drain, rail-to-rail characteristics. Specific voltage, current, timing, temperature, and logic-threshold values were not included in the provided data and therefore require verification from the manufacturer datasheet before design release. A voltage comparator is an analog semiconductor that compares two input voltages and produces a logic-level indication of their relationship. The LM293N contains two independent comparators, allowing one package to implement threshold detection, window comparison, free-running oscillator, or simple analog-to-logic conversion. Within the broader hierarchy, it is a comparator IC, then an analog integrated circuit, and finally a semiconductor. Its open-collector outputs can sink external current and normally require a pull-up resistor when the design expects a high-level output. The primary documented feature is its ability to operate from a single supply over a wide range of voltages, with split-supply operation also supported. The two independent channels provide design flexibility for comparing a sensor against a reference, checking a power rail, or generating complementary decisions in control circuitry. The open-collector architecture can support wired logic and level translation, but the external pull-up, output current, propagation delay, and input common-mode limits must be checked against the actual datasheet. LM293N is suitable for industrial control, instrumentation, power-supply supervision, sensor interfaces, and embedded threshold detection. In a single-supply circuit, place the input network so that the signal remains within the device's verified common-mode range. In a split-supply circuit, confirm the positive and negative rail limits and the permitted total voltage. Because the provided data does not state absolute maximum ratings, supply voltage, input offset, output-current capability, response time, or operating temperature, those values should not be assumed. Design practice should include a local bypass capacitor, a defined pull-up resistor for each open-collector output, and protection for exposed sensor inputs. Avoid relying on an output high level until the pull-up network and downstream load have been analyzed. Verify input polarity, output inversion, hysteresis, and logic compatibility with the system controller. The 8-DIP package is mechanically important: use the manufacturer pinout and maintain adequate lead spacing during assembly. This page combines the verified LM293N product identity, package information, application context, datasheet links, and engineering considerations.

LM293P - Dual 36V Differential Comparator | Texas Instruments

Texas Instruments LM293P is a dual differential comparator rated for a 2 V to 36 V supply range, with a stated propagation delay of 300 ns, packaged as an 8-pin PDIP. Each channel provides independent differential inputs and an open-collector output, making the device suitable for threshold detection, level translation, relay driving, and industrial control logic. A differential comparator is an analog integrated circuit that compares two input voltages and changes its output state according to their relative polarity. The LM293 belongs to the comparator hierarchy, which sits within linear and mixed-signal ICs. Its open-collector outputs can sink current from a pull-up network, allowing the outputs to be wired together when wired-OR operation is required. The principal features of the LM293P are its dual-channel architecture, differential input arrangement, wide 2 V to 36 V operating supply range, open-collector outputs, and 300 ns response time. The package is an 8-pin PDIP, providing a through-hole footprint suitable for prototypes, legacy industrial equipment, repair assemblies, and applications where leaded components are preferred. The LM293 contains two electrically independent comparator channels. Differential inputs are presented through inverting and non-inverting pins, while the output uses an open-collector transistor capable of pulling the output node toward ground. A pull-up resistor is required to establish a high output level, and the output stage can sink current from TTL, CMOS, and other logic families within the device's stated operating limits. Typical uses include monitoring a control or battery voltage against a reference, detecting sensor crossings, implementing overvoltage and undervoltage protection, driving relay or indicator circuits, and providing threshold-compatible interfaces between analog and digital systems. Because the device supports a wide supply range, it can also be used in industrial systems operating from conventional low-voltage DC rails. Designers must provide the required output pull-up and verify input common-mode limits, output-current limits, and operating temperature against the manufacturer datasheet. Input protection, bypassing, and leaded-component spacing should also be considered when the LM293P is used in high-noise or high-voltage surroundings. This page combines verified manufacturer and distributor information with package-level selection guidance, verified drop-in candidates, application use cases, and practical design notes. It is intended to help engineers identify whether the LM293P fits an existing 8-pin comparator design without confusing electrically related but mechanically different packages.

LM293QT

LM293QT - Dual Low-Power Wide-Supply Comparator | STMicroelectronics

The STMicroelectronics LM293QT is a dual general-purpose comparator designed for low-power operation from a single supply or split supplies. The device provides two independent comparator channels, a wide single-supply operating range of 2 V to 36 V, and an open-collector output configuration. It is packaged in an 8-UFDFN package with a 2 mm x 2 mm body size. The LM293QT is suited to voltage-level detection, threshold comparison, industrial control logic, sensor interfaces, and low-current signal conditioning where a compact, low-power comparator is required. An analog comparator is an integrated circuit that evaluates two input voltages and changes its output state when the voltage at the non-inverting input becomes higher than the voltage at the inverting input. The LM293 family belongs to the comparator and linear IC hierarchy, where each independent channel compares its differential input while operating from a common supply. This makes the device useful between sensors and digital control systems, where a small voltage difference must be converted into a logic-compatible indication. The principal electrical characteristics include a 2 V to 36 V single-supply range, operation from split supplies of plus or minus 1 V to plus or minus 18 V, and very low supply current of approximately 0.45 mA. The comparator channels feature low input bias current of approximately 20 nA. The open-collector output stage allows the output to be pulled up to an external supply and enables wired-AND behavior when multiple comparator outputs are connected. The output type is suitable for interfacing with open-drain or open-collector digital devices. The LM293QT provides two independent channels in a compact 8-UFDFN package. The wide supply range allows operation from low-voltage systems through higher industrial rails, while the low supply current supports battery-operated and always-on equipment. The two channels can be used for independent threshold decisions, window monitoring, or complementary comparisons. Open-collector outputs require an external pull-up resistor when the output must rise to a defined logic-high voltage. Typical applications include industrial sensor interfaces, battery monitoring, power-supply sequencing, overvoltage and undervoltage detection, temperature-controller signal conditioning, and embedded threshold logic. Because the input common-mode range can include ground, the LM293QT is particularly useful in systems where the signal being monitored is close to the negative supply rail. When laying out a design, preserve the exposed-pad and package thermal requirements of the 8-UFDFN package. Route the comparator inputs away from switching nodes and high-current output paths, and place the input and output components close to their associated pins. Choose the external pull-up voltage and resistor to match the receiving logic, and verify that the output sink current remains within the device limits for the selected pull-up network.

LM321MF/NOPB - 1MHz, Single Op Amp, 3-32V, SOT-23-5 | TI

The Texas Instruments LM321MF/NOPB is a single-channel, low-power operational amplifier delivering 1 MHz unity-gain bandwidth and 0.4 V/us slew rate in a 5-pin SOT-23 (DBV) package. It operates from a single 3 V to 32 V supply (or dual +/-1.5 V to +/-16 V) and supports an input common-mode range that includes ground, enabling true single-supply operation. Housed in the industry-standard SOT-23-5 footprint, the LM321MF/NOPB combines economy with TI's LM321 bipolar architecture originally developed by National Semiconductor. An operational amplifier (op amp) is a high-gain DC-coupled electronic voltage amplifier with differential inputs and a single-ended output. Op amps belong to the amplifier IC family within integrated circuits, which also includes instrumentation amplifiers, comparators, and specialty audio/video amplifiers. The LM321MF/NOPB specifically is a general-purpose single op amp, meaning one amplifier channel per package; it sits in the hierarchy: op amp -> amplifier IC -> analog IC -> integrated circuit -> semiconductor. Key features include 1 MHz gain-bandwidth product, 0.4 V/us slew rate, low input offset voltage (typical 2 mV), input common-mode range that includes the negative rail, and large capacitive-load drive capability. The bipolar input stage with class-AB output provides robust performance across the wide 3 V to 32 V supply range. Internal ESD protection and thermal shutdown enhance field reliability. The LM321MF/NOPB uses a bipolar transistor input stage rather than CMOS or JFET, giving it inherently low noise voltage density but somewhat higher input bias current than modern CMOS alternatives. Its wide supply range allows direct connection to industrial 24 V rails, 12 V battery systems, or +/-15 V analog supplies, eliminating the need for additional level shifters. The 1 MHz bandwidth is sufficient for audio, sensor conditioning, and many active-filter topologies. Typical applications include transducer signal conditioning, low-frequency active filters, current sensing with high-side or low-side shunt, audio pre-amplifier stages, and general-purpose amplification in industrial controls. The SOT-23-5 footprint is ideal for space-constrained PCB designs such as handheld instruments and IoT sensor modules. When designing with the LM321MF/NOPB, verify input bias current (45 nA typical) is acceptable for high-impedance sensor interfaces. Place a 0.1 uF decoupling capacitor close to the VCC pin and ensure output capacitive loads stay within the datasheet's stability region to avoid oscillation. This page synthesizes distributor pricing, drop-in SOT-23-5 alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a faster path from datasheet to prototype.

LM324AD

LM324AD - Quad 30V 1.2MHz Op Amp | Texas Instruments

Texas Instruments LM324AD is a general-purpose quad operational amplifier containing four independent, internally frequency-compensated amplifiers. The device supports a 30 V maximum supply, operates at a gain-bandwidth product of 1.2 MHz, and has a 3 mV input offset voltage rating. It is supplied in a 14-pin SOIC package, enabling one component to provide four amplified channels in a compact surface-mount footprint. The LM324 family is designed for single-supply operation over a wide voltage range, while also supporting split-supply arrangements when the circuit requires a bipolar input or output range. An operational amplifier is an analog signal-processing IC that uses high-gain differential amplification to increase the voltage presented at its input. The LM324 belongs to the general-purpose amplifier segment of the larger voltage-feedback operational-amplifier hierarchy. Internally compensated amplifiers simplify closed-loop design because no external frequency-compensation components are required for ordinary gain configurations. Four independent amplifiers in one package reduce board area and component count in multi-channel sensor, filtering, buffering, and control circuits. The verified product information identifies four amplifier circuits, a 1.2 MHz gain-bandwidth product, a 3 mV offset-voltage rating, and operation from a supply as high as 30 V. The internal compensation supports stable operation in standard noninverting and inverting amplifier arrangements. Because the LM324AD is a general-purpose device, design engineers should treat it as a cost-conscious solution rather than a precision op amp with rail-to-rail outputs, low offset over temperature, or very low noise. Common uses include buffering sensor outputs, amplifying low-level control signals, active filtering, differential signal conditioning, and driving ADC input stages. The four independent channels can process separate analog signals or implement stages such as a two-stage filter or transimpedance-style front end. Single-supply operation is particularly useful in industrial controls, embedded instrumentation, educational electronics, and simple battery-powered systems where a negative rail is unavailable. When using the LM324AD, verify input and output common-mode limits, output-current capability, load impedance, and stability under the selected closed-loop gain before finalizing the design. Place input and output compensation or decoupling components close to the relevant pins, keep sensitive input routing away from switching nodes, and include adequate bypassing on the power supply. The 14-pin SOIC package also requires attention to thermal pad-free layout and copper continuity when operating at high ambient temperatures. This product page combines verified manufacturer and distributor information, lifecycle-oriented sourcing details, same-footprint alternatives, and practical design guidance. It adds a same-package comparison framework and implementation notes that are more useful for PCB and sourcing decisions than a distributor listing alone.

LM324ADE4

LM324ADE4 - Quad 1.2MHz Op Amp | Texas Instruments | SOIC-14

Texas Instruments LM324ADE4 is a quad general-purpose operational amplifier with four independent, internally frequency-compensated amplifiers, 1.2 MHz gain-bandwidth product, and 0.5 V/µs slew rate in a 14-pin SOIC package. The device operates from a single supply or split supplies, with the listed operating range extending to ±16 V. An operational amplifier is an analog signal-conditioning IC that compares two input voltages and amplifies their difference through high open-loop gain. The LM324ADE4 belongs to the operational-amplifier hierarchy within amplifier ICs and analog semiconductors. Its four independent channels allow one package to provide feedback control, buffering, level shifting, summation, and general analog amplification without requiring four separate amplifier packages. The four amplifiers feature internally frequency compensation, allowing operation as stable unity-gain buffers without external compensation components. A 1.2 MHz gain-bandwidth product and 0.5 V/µs slew rate support audio-band and general-purpose closed-loop applications. The device also supports operation from a single positive supply as well as split bipolar supplies, making it useful in mixed industrial, instrumentation, control, and consumer circuits. The 14-SOIC package is pin-compatible with the established LM324 family arrangement, which simplifies repair, prototyping, and board reuse. Each amplifier has differential inputs, an output, and power connections, with the package distributing those functions across four channels. Because the amplifiers are independent rather than sharing internal output stages, each channel can be used for a separate signal path or left unused when its input and output are properly configured. Typical uses include sensor-signal conditioning, low-current motor and actuator drivers, audio preamplification, analog summing networks, threshold detection, and general instrumentation. The 1.2 MHz bandwidth is adequate for many audio and control signals, but designs requiring substantially higher bandwidth, lower offset voltage, faster settling, or lower noise should use a more specialized amplifier family. Design carefully around input common-mode range, output swing, input bias current, and the limits of each amplifier channel. Keep sensitive inputs away from noisy return paths, observe the recommended bypass capacitors at the supply pins, and avoid operating near the output saturation limits. The manufacturer datasheet should guide input/output protection, supply decoupling, unused-channel configuration, and maximum input and output voltage conditions. This product page combines the LM324ADE4 operating parameters, package details, practical application guidance, pin-focused design considerations, and qualified drop-in alternatives. It is intended to help engineers identify where this economical quad general-purpose amplifier fits and where a higher-performance or application-specific amplifier is more appropriate.

LM324ADR2

LM324ADR2 - 3-32V Quad 1MHz Op Amp | onsemi

The onsemi LM324ADR2 is a general-purpose, single-supply quad operational amplifier with four amplifier circuits, a 3 V to 32 V supply range, 1 MHz gain-bandwidth product, and a maximum input offset voltage of 3 mV, housed in a 14-pin SOIC package. The device supports true differential inputs and combines four amplifiers in one package, reducing board area in cost-sensitive analog signal-conditioning systems. An operational amplifier is an amplifier IC that uses high open-loop gain and negative feedback to amplify the difference between two input voltages. The quad configuration places four amplifiers in one device, making it widely used in general-purpose signal conditioning, sensor interfaces, filtering, and control systems. Within the electronics hierarchy, an operational amplifier is a linear amplifier IC and a building block for analog signal-processing circuits. Key characteristics include four amplifier sections, operation from 3 V to 32 V, a 1 MHz gain-bandwidth product, and a 3 mV maximum input offset voltage. The wide supply-voltage range allows the LM324ADR2 to operate from common low-voltage supplies as well as higher-voltage industrial rails. Its internal input-stage characteristics are designed for general-purpose applications rather than high-speed precision signal paths. The quad architecture consolidates four amplifiers into one 14-pin SOIC package. This can simplify PCB layouts and reduce component count in designs requiring several independent analog channels. Because all four sections share one package and supply connection, engineers must still consider common supply-current variation, thermal behavior, ground routing, and channel-to-channel performance when planning precision measurements. Typical uses include low-frequency sensor amplification, audio preamplification, DC signal conditioning, active filtering, voltage comparison, and industrial control interfaces. The 1 MHz gain-bandwidth product is appropriate for signals well below its upper bandwidth limit, while the 3-32 V operating range supports both compact low-voltage systems and higher-voltage industrial electronics. For reliable layout, route analog inputs and feedback connections away from switching-current paths, connect the ground reference properly, and place input and output bypass capacitors close to the device. Avoid using the LM324ADR2 where very low offset, very low bias current, rail-to-rail output swing, or high-speed closed-loop performance is required without first checking the full operating conditions. This page organizes the LM324ADR2 electrical characteristics, package information, drop-in candidates, application guidance, and design notes into a practical engineering reference for analog designers.

LM324ADR2G

LM324ADR2G - Quad Op Amp, 3-32V, 1MHz SOIC-14 | onsemi

The onsemi LM324ADR2G is a low-cost quad operational amplifier with four independent general-purpose amplifier circuits, true differential inputs, a supply range of 3V to 32V single-supply (or ±1.5V to ±16V split supply), a 1 MHz gain-bandwidth product, and a 0.6 V/µs slew rate, housed in a 14-pin SOIC package supplied on tape and reel. A quad operational amplifier is an integrated circuit that packs four identical, frequency-compensated op amp stages onto a single silicon die, sharing one set of power pins. Within the amplifier hierarchy, it belongs to the general-purpose bipolar op amp family: operational amplifier -> linear amplifier IC -> analog signal conditioning IC. Quad op amps reduce board area, cut per-channel cost, and improve channel-to-channel thermal matching versus four single op amps. Key features include single-supply operation down to 3V with input common-mode range that includes ground - the defining trait that made the LM324 the industry-standard quad op amp. The A-grade suffix guarantees a maximum input offset voltage of 3 mV, tighter than the base LM324. Internally frequency compensation eliminates external compensation components, and the low supply current of approximately 700 µA per amplifier (typical for the family) suits battery-powered designs. Technically, the LM324ADR2G uses a mature bipolar process with PNP input stages that enable ground-sensing inputs. The output stage is a classic single-ended Class-AB emitter follower, which means it can sink only limited current near ground and exhibits output crossover behavior under light loads - a known characteristic designers must account for in precision or audio paths. Typical applications include transducer signal conditioning, DC gain blocks, active filters, comparators, voltage followers, and industrial sensor interfaces where single-supply, ground-referenced inputs simplify the power architecture. Design consideration: keep total supply voltage within 32V, and remember the output cannot swing rail-to-rail - headroom of roughly 1.5V to the positive rail is required at moderate loads. This page adds value beyond the manufacturer datasheet by synthesizing distributor pricing, verified drop-in alternatives, a parametric comparison table, and practical design notes in one place.

LM324ADRE4

LM324ADRE4 - Quad 1.2MHz Op Amp in 14-SOIC | Texas Instruments

Texas Instruments LM324ADRE4 is a quadruple general-purpose operational amplifier with four independent amplifier channels, a 1.2 MHz gain-bandwidth product, and a 0.5 V/us slew rate. The device operates from ±1.5 V to ±16 V and is packaged in a 14-pin SOIC. An operational amplifier is an analog signal-conditioning semiconductor that amplifies the difference between its inverting and non-inverting inputs. The LM324 belongs to the general-purpose op-amp hierarchy, combining four amplifiers in one integrated circuit. This integration reduces board area and simplifies designs requiring multiple low-frequency signal channels, such as sensor conditioning, audio paths, data acquisition, and industrial control loops. Each channel supports single-supply or dual-supply operation. Key characteristics include a 1.2 MHz gain-bandwidth product, 0.5 V/us slew rate, and a supply-voltage range of ±1.5 V to ±16 V. The four-channel architecture makes the device useful for amplifier arrays, active filters, comparators, buffer stages, and transducer interfaces. The 14-pin SOIC is a standard surface-mount package suitable for conventional PCB assembly and rework. The LM324ADRE4 is designed for general-purpose applications where a wide bandwidth, adequate slew rate, and economical quad integration are more important than low offset voltage, rail-to-rail output, or high precision. Its 14-pin package provides one amplifier section per three-and-a-half pins, with the positive supply connected to pin 4 and the negative supply connected to pin 11 in the standard dual-supply configuration. Grounding the negative supply pin permits single-supply operation when the signal and output remain within the usable common-mode range. Typical uses include low-frequency audio amplification, sensor signal conditioning, active filter stages, voltage followers, comparators, and general instrumentation. In multi-stage designs, the four channels can implement cascaded gain, summing, difference, or buffering functions while reducing component count. Independent amplifier sections also allow unused channels to be configured conservatively rather than left floating. Layout should keep feedback resistors and input traces close to the device, maintain short return paths to the supply ground, and place input bypass capacitance near the supply pins. Check output-current and capacitive-load limits for the selected operating condition. Because the LM324 is a general-purpose amplifier rather than a precision or rail-to-rail part, verify input common-mode range, output swing, offset, and noise requirements against the actual signal. This page combines the manufacturer-family specifications with same-package alternatives, a parameter comparison, and practical PCB guidance. It is designed to support quick part selection while directing engineers to the manufacturer datasheet and pin-description table for final circuit qualification.

LM324ADRG4

LM324ADRG4 - 1.2MHz Quad Op Amp, 14-SOIC | Texas Instruments

Texas Instruments LM324ADRG4 is a standard general-purpose, four-circuit operational amplifier in a 14-pin SOIC package. Each circuit has a 1.2 MHz gain-bandwidth product, 0.5 V/us slew rate, and operation from single or split supplies over a ±1.5 V to ±16 V range. The four amplifiers are independent, high-gain, frequency-compensated stages designed for general-purpose signal conditioning. An operational amplifier is an amplifier IC used within a feedback network to control gain, amplify differential signals, buffer inputs, perform comparisons, or drive analog stages. The LM324 belongs to the operational-amplifier hierarchy, which includes amplifier ICs, analog signal-chain ICs, and semiconductor devices. Its ability to operate from a single supply makes it useful in battery-powered, industrial-control, instrumentation, and consumer circuits where one supply rail is more practical than split bipolar rails. The LM324 family's key characteristics include a typical supply-current drain of 0.8 mA and a common-mode input-voltage range that includes ground. These characteristics support low-power analog designs where the input signal may approach the lower supply rail. Each amplifier is frequency compensated, reducing the external compensation components normally required in precision applications. The 1.2 MHz bandwidth is sufficient for general-purpose audio, control, sensing, and signal-shaping stages but is not intended for high-speed data acquisition or demanding wideband filtering. Typical uses include current sensing around a low-side shunt, low-side transistor control, sensor amplification, audio channels, and general-purpose buffering. The 14-SOIC package provides a conventional through-hole-compatible footprint for PCB assembly. Because each of the four amplifier sections is independent, unused sections should be configured according to the manufacturer's recommended practice rather than left floating. A key design consideration is the input common-mode range. The LM324 can accept inputs that include ground, making it suitable for many single-supply circuits, but it cannot swing all the way to the positive supply rail. Output swing, load capability, and input bias behavior must therefore be checked against the actual signal range. Decoupling should follow the manufacturer circuit recommendations, with short supply traces and a local bypass capacitor helping maintain stable operation. This product record combines the verified LM324ADRG4 electrical ratings, package information, sourcing links, pin-compatible family options, and practical design guidance. It also distinguishes true same-footprint alternatives from related amplifier families that differ in electrical behavior, qualification, package, or pin assignment.
