The device provides four independent amplifiers in one package, making it suitable for signal conditioning, sensing, buffering, and control circuits where component count and board area are important. An operational amplifier is an analog signal-processing IC that amplifies the voltage difference between its inverting and non-inverting inputs. The quad operational-amplifier category combines four amplifiers in one package, while the broader hierarchy includes voltage-feedback amplifiers, analog amplifiers, and integrated circuits. This makes the LM2902KAVQPWRQ1 useful wherever several low-to-moderate-bandwidth analog channels must operate from the same supply. Automotive qualification is a defining feature of the LM2902-Q1 family. According to the Texas Instruments LM2902-Q1 product information, the LM2902-Q1, LM2902B-Q1, and LM2902BA-Q1 devices are qualified in accordance with AEC-Q100 specifications. Other key characteristics include 2 kV improved ESD capability, a 0.5 V/µs slew rate, and an input common-mode voltage range that includes ground. The latter supports practical single-supply designs when the signal remains near the lower supply rail. The KAV version combines the standard bipolar amplifier architecture with 1.2 MHz gain-bandwidth performance and 2 mV offset voltage. Its four amplifier sections share the positive and negative supply pins, while each section retains its own input and output terminals. A gain-bandwidth product near 1.2 MHz supports general-purpose closed-loop operation well below the amplifier's upper frequency limit, depending on feedback topology and acceptable phase margin. Typical uses include automotive sensor interfaces, low-frequency active filters, transimpedance amplifiers, audio signal conditioning, battery monitoring, actuator drivers, and general analog control loops.

The Texas Instruments LM2902KD is a quad general-purpose operational amplifier in a 14-pin SOIC package. Each of its four amplifiers supports a maximum supply voltage of 26 V, operates at a typical gain-bandwidth product of 1.2 MHz, and includes improved electrostatic-discharge protection rated to 2 kV. The device is designed for industrial and general-purpose analog signal-conditioning circuits that require four amplifiers in one package. An operational amplifier is a voltage-amplifying component whose open-loop gain is controlled by external feedback. In a closed-loop circuit, negative feedback establishes the actual gain and improves linearity, while the internal architecture provides high input impedance and low output impedance. The LM2902KD belongs to the operational-amplifier hierarchy within analog and mixed-signal semiconductors, combining four amplifier channels in one package to reduce board area and simplify multi-channel designs. Key characteristics include four amplifier circuits, a 26 V maximum supply rating, a 1.2 MHz typical gain-bandwidth product, and 2 kV improved ESD protection. The listed input offset voltage is typically 3 mV, while typical input offset current is 2 nA. Typical supply-current drain is 0.8 mA per amplifier. These specifications make the device suitable for sensor interfaces, low-frequency signal conditioning, active filters, and industrial control applications where a robust, economical quad amplifier is preferred. The LM2902 family uses internal frequency compensation, allowing operation as a unity-gain amplifier without external compensation components. Its common-mode input voltage range includes ground, which supports direct sensing of low-side signals near the lower rail. This characteristic is useful in battery-powered, transducer, and grounded-source systems where the input signal can approach the supply floor. Typical applications include four-channel sensor conditioning, process-control instrumentation, current-loop receivers, audio preamplifier stages, active filters, and general buffer or gain stages. Because the device is specified for a 26 V maximum supply, it should not be treated as a 36 V part even though closely related LM2902B-family devices may support a wider supply range. Designers should verify common-mode range, output swing, input bias behavior, and channel-to-channel variation against the exact operating conditions. Decoupling capacitors should be placed close to the supply pins, and unused amplifier channels should be configured according to the manufacturer’s stability recommendations rather than left with floating inputs.

LM2902KDG4

LM2902KDG4 - Quad 26V 1.2MHz Op Amp | Texas Instruments

Texas Instruments LM2902KDG4 is a general-purpose quad operational amplifier with four amplifier channels, a 26 V maximum supply rating, 1.2 MHz gain-bandwidth performance, and improved 2 kV ESD protection. The device is supplied in a 14-pin SOIC package measuring 0.154 inch, or 3.90 mm, in body width. Each channel provides the standard differential-input, single-ended-output operational-amplifier arrangement. An operational amplifier is an analog integrated circuit that compares voltages applied to its inverting and non-inverting inputs and produces an output voltage representing that difference. When negative feedback surrounds the amplifier, it forms the core building block of voltage amplifiers, current buffers, comparators, filters, integrators, and sensor-conditioning circuits. The LM2902K places four such channels in one package, allowing a compact design to handle several independent low-frequency analog signals. The quad configuration provides four channels, 26 V maximum supply voltage, and 1.2 MHz gain-bandwidth product. These characteristics make the LM2902KDG4 suitable for general-purpose signal conditioning where the required signal bandwidth is below the amplifier's 1.2 MHz unity-gain capability. Its 2 kV improved ESD capability provides additional protection against electrostatic discharge encountered during handling or installation. The 14-SOIC construction is appropriate for conventional through-hole board assembly because the leads extend from the sides of the package. A quad package also reduces the number of amplifier packages required when a design needs four channels. Channel assignment and electrical behavior should be confirmed against the manufacturer pin-description table before PCB routing, particularly for power pins, input pins, and output pins. Typical uses include audio preamplification, instrumentation-signal conditioning, active filtering, transducer amplification, analog control loops, and general sensor interfaces. In a typical application, the LM2902KDG4 can amplify a low-level sensor signal, buffer an analog source, or implement an active filter with external resistors and capacitors. Common-mode range, input bias current, output swing, and stability requirements must be checked against the actual circuit. A key design consideration is power-supply bypassing. Place the required bypass capacitors close to the supply pins and route the ground return directly to the device ground. Avoid long analog traces, maintain a stable reference for each feedback network, and verify that the selected feedback and compensation values support the intended closed-loop bandwidth at the 1.2 MHz gain-bandwidth product. This product record combines the exact ordering information for LM2902KDG4 with package identification, lifecycle context, verified manufacturer characteristics, sourcing guidance, and engineering-oriented comparison information.

It combines low-noise performance with wide supply-voltage tolerance, making it suitable for industrial, automotive, and general analog signal-conditioning systems. An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. In its noninverting configuration it gains a signal applied to the positive input; in its inverting configuration it amplifies the input applied through the feedback network to the negative input. The LM2902K belongs to the hierarchy of operational amplifier, analog amplifier, linear amplifier, and semiconductor, while supporting applications from sensing and filtering to instrumentation and actuator control. Four independent amplifiers are integrated in one 14-pin SOIC, reducing board area compared with four single-amplifier packages. Each channel is frequency compensated and can operate from a single or split supply. According to the Texas Instruments product page, the device is a quad, 26 V, 1.2 MHz operational amplifier with improved 2 kV ESD protection. The four-channel organization is useful when a system requires several similar low-frequency amplification, buffering, or differential-input functions. The LM2902 architecture is intended for dependable, cost-conscious general-purpose analog designs rather than precision or high-speed signal chains. Its 1.2 MHz bandwidth supports moderate-frequency closed-loop operation, while the high-gain internal stages help implement common amplifier topologies. Split-supply operation is particularly useful in bipolar sensor circuits, where signals may be centered around 0 V and require both positive and negative output swing. Typical uses include industrial sensor interfaces, transducer conditioning, loop filtering, audio preamplification, automotive signal processing, and four-channel active filtering. The device can also implement comparators in applications where the response-speed requirements are modest and the input common-mode range is adequate. Each amplifier is independent, allowing unused channels to be configured according to the manufacturer's recommended stability practices. For PCB design, place the device to minimize noise-sensitive input routing and keep feedback traces short. Decoupling capacitors should be positioned close to the supply pins, while input and feedback paths should avoid nearby switching nodes and high-current return paths. Stable operation depends on choosing the correct feedback network and observing the input common-mode and output-swing limits for the selected supply voltage. This page organizes the device specifications, replacement options, application guidance, and practical design notes into a concise engineering reference. It also distinguishes true package-compatible alternatives from merely functional equivalents so replacement decisions can be checked against footprint, pinout, and operating requirements.

LM2902KPWE4

LM2902KPWE4 - Quad 1.2MHz Op Amp, 26V, 14-TSSOP | Texas Instruments

The Texas Instruments LM2902KPWE4 is a quadruple general-purpose operational amplifier with a 1.2 MHz gain-bandwidth product, a 26 V maximum supply rating, and four independent amplifiers in a 14-pin TSSOP (PW) surface-mount package. An operational amplifier is a voltage-gain building block that amplifies the difference between two input voltages. A quad device packages four amplifiers sharing one supply pin and one ground pin, which cuts board area roughly in half compared with four single amplifiers and keeps sensitive analog channels on a common reference. Quad op amps sit in the hierarchy above single and dual amplifiers and below application-specific amplifiers, and they belong to the broader class of analog signal-conditioning integrated circuits used in nearly every industrial, automotive, and instrumentation design. Key features of the LM2902KPWE4 include a 1.2 MHz gain-bandwidth product that supports operation from DC to several hundred kHz of closed-loop bandwidth, a 26 V maximum total supply voltage for wide input swing, and improved ESD protection rated to 2 kV per the Texas Instruments LM2902K family description. The part is qualified to AEC-Q100 for automotive applications, and the E4 orderable suffix denotes the RoHS-compliant, lead-free finish. The 14-TSSOP body measures 0.173 inch (4.40 mm) wide, so the part fits the same footprint as other TI quad op amps such as the LM2902KPW. Architecturally the LM2902K family is a classic bipolar general-purpose amplifier stage with internal biasing, designed for single or dual supply operation and for driving typical resistive and capacitive loads within the output swing limits. Because it is a general-purpose part rather than a rail-to-rail precision amplifier, design work must confirm that the input common-mode range and output swing are adequate for the signal chain in question, and that the amplifier is stable with the output load capacitance present on the board. Typical uses include sensor signal conditioning, transducer and bridge-amplifier front ends, audio mixer sub-circuits, industrial loop-current receivers, and general instrumentation where four channels of gain are needed on a single board. Two channels can also be cross-coupled to build a higher-gain stage or an instrumentation-style front end. One key design consideration is that a 26 V supply capability does not mean the amplifier should be operated near 26 V: supply noise, output stage distortion, and device stress all rise as the rail voltage increases. Keep the supply within the intended range and decouple close to the supply pins with a 0.1 uF ceramic plus a bulk capacitor. This page brings together the manufacturer ordering information, drop-in replacement options in the same TSSOP-14 footprint, and applied design guidance for layout, decoupling, and stability that goes beyond the basic ordering table.

Its 2 mV input offset specification supports accurate amplification of low-level signals, while the four-channel configuration reduces package count on analog-conditioning boards. The 26 V maximum supply rating provides additional input-voltage margin in automotive systems that operate from a 12 V battery through transient and filtering networks. Internally, each amplifier stage provides high open-loop gain and frequency compensation, allowing stable operation without an external compensation capacitor in ordinary closed-loop configurations. The amplifier can operate from a single positive supply or from split positive and negative supplies. Input bias current of approximately -0.5 µA and the stated CMRR characterize the input stage, helping engineers evaluate source-impedance matching and common-mode noise rejection before selecting external resistor networks. Typical uses include automotive sensor interfaces, battery monitoring, active filtering, actuator-signal conditioning, instrumentation amplifiers, and general-purpose analog control loops. The four channels can independently implement gain stages, buffers, comparators using suitable feedback arrangements, or voltage followers. Its SOIC-14 format supports conventional surface-mount assembly while providing enough pins for the four conventional dual-input amplifier channels and the two supply terminals. Design around the 26 V supply limit, maintain the required common-mode and output-voltage ranges, and account for input bias current when using high-source-impedance sensors. Decoupling capacitors should be placed close to the supply pins, and sensitive analog inputs should be routed away from switching nodes. Verify startup, shutdown, capacitive-load stability, and thermal performance in the final automotive environment rather than relying only on nominal amplifier parameters. This page combines the exact orderable MPN, automotive-family positioning, pin-level implementation guidance, drop-in comparison data, and application-focused design guidance to support faster component evaluation and PCB-level planning.

The verified product data identifies it as a standard general-purpose amplifier with a 26 V maximum supply, 1.2 MHz gain-bandwidth product, and typical input offset voltage of 2 mV. It is designed for cost-sensitive analog signal-conditioning circuits that require more than one amplifier in a compact surface-mount package. An operational amplifier is an amplifier IC that uses high open-loop gain and negative feedback to control gain accurately. A quad device integrates four amplifiers, reducing package count and simplifying layouts requiring several channels. The LM2902 family belongs to the operational-amplifier hierarchy and supports common analog functions such as signal amplification, buffering, active filtering, comparisons, transducers, and low-frequency closed-loop control. The key headline characteristics are four amplifier circuits, a 26 V supply rating, 1.2 MHz gain-bandwidth product, 2 mV typical offset voltage, and a 14-pin SOIC package. Internal frequency compensation makes each channel suitable for many unity-gain or moderate-gain applications without an external compensation network. On-chip capacitors in each amplifier support stable operation as a general-purpose voltage-feedback amplifier. The architecture follows the classic high-voltage, internally compensated operational-amplifier approach. Four independent amplifiers share one monolithic substrate but do not share internal signal paths. This allows the same device to implement four separate channels, such as a dual-sensor front end or two complete analog-processing chains. The verified data does not provide exact input bias current, output-current capability, slew rate, or common-mode limits, so those specifications require confirmation from the selected manufacturer's datasheet. Typical uses include industrial sensor interfaces, low-frequency active filters, audio preamplifier stages, process-control modules, instrumentation, and general buffer or gain stages. The quad organization is particularly useful when four similar analog functions must fit on a PCB. Actual circuit suitability depends on supply voltage, source impedance, load impedance, signal frequency, output swing, stability, and thermal conditions. For PCB design, place the device so sensitive analog inputs remain short and route outputs away from switching nodes and high-current paths. Bypass each supply connection near the package with suitable decoupling, maintain a common ground reference, and verify unused-channel inputs are biased so they do not float. The SOIC package also requires a thermal strategy when nearby circuitry drives substantial channel dissipation.

Typical uses include low-frequency process-control loops, sensor amplifiers, analog monitoring channels, buffered instrumentation inputs, and small-signal conditioning stages. The quad organization is especially helpful in equipment that must process several transducers or supply and return signals, such as data-acquisition modules, industrial controllers, test equipment, and communication or power-management interface boards. A key design practice is to verify the complete operating envelope rather than relying only on the 1 MHz bandwidth designation. Input signals must remain within the amplifier's valid common-mode range, output loading must remain within its drive capability, and power-supply bypassing should be placed close to the supply pins. Decoupling values, stability requirements, and output-load restrictions should follow the datasheet and the intended feedback configuration.

This architecture favors straightforward implementation over the flexibility offered by externally compensated amplifiers. Typical uses include low-frequency sensor conditioning, transducer amplification, analog summing and comparison stages, active filtering, instrumentation buffers, and industrial control interfaces. Four integrated channels can reduce the component count in designs that require multiple amplifier functions. When one channel is used for a critical precision path, the other channels must still meet the same supply and stability constraints, making common-layout and simultaneous-signal behavior important design considerations. A key design consideration is power-supply range. Although the device supports supplies up to 26 V, input and output voltage limits must be respected during startup, shutdown, and transient conditions. Decoupling capacitors should be placed close to the supply pins, while input sources should avoid excessive capacitance unless its effect on stability is evaluated. The 14-pin TSSOP footprint also requires attention to thermal dissipation and copper routing during assembly.

A broad common-mode input range and single-supply capability make the device practical for circuits powered from industrial and automotive-style rails. The LM2902MX uses a bipolar amplifier architecture. Internal frequency compensation stabilizes operation at unity gain and simplifies PCB implementation, but the device is intended primarily for lower-frequency analog signals rather than high-speed signal chains. Its 1.2 MHz gain-bandwidth product should be considered when selecting closed-loop gain because bandwidth decreases as gain increases, which can affect signal rise time, phase margin, and loop stability. Typical uses include transducer-signal conditioning, industrial sensor interfaces, current-loop receivers, audio preamplification, analog-control feedback networks, and four-channel instrumentation systems. Multiple independent amplifier sections can process related signals without requiring four separate packages, reducing board area and simplifying power distribution. The quad organization is particularly useful when a design repeats the same amplifier topology across several measurement or control channels.

Its high-voltage operating capability makes it useful in industrial control, instrumentation, sensor conditioning, audio, and power-supply feedback circuits. The LM2902MX/NOPB is identified as a standard general-purpose amplifier, while the LM2902 family is also described as a quad, 26 V operational amplifier with 1.2 MHz bandwidth. An operational amplifier is an analog signal-conditioning integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. The LM2902 contains four independent amplifier sections with internal frequency compensation, allowing stable operation in common noninverting, inverting, summing, comparator, and feedback configurations. Its low-power design is intended for battery-powered and general-purpose systems where a wide supply-voltage range is more valuable than high-speed performance. Key features include a 3 V to 32 V single-supply operating range, a 26 V maximum total supply voltage, 1.2 MHz gain-bandwidth product, 2 mV typical input offset voltage, and approximately 0.5 V/us slew rate. The four-channel architecture reduces component count and board area when multiple analog signals require conditioning. The 14-pin SOIC package is also available in related LM2902 order variants, making footprint planning important when selecting an exact replacement. The LM2902 family uses a bipolar voltage-feedback architecture. Internal compensation removes the need for an external frequency-compensation capacitor in typical closed-loop configurations. The device can operate from a single positive supply or from split positive and negative supplies. Its relatively modest bandwidth makes it appropriate for slower control and measurement loops rather than high-speed video, RF, or precision signal-chain applications. Typical uses include transducer and sensor conditioning, low-frequency active filters, current-loop and voltage-feedback control, audio preamplification, battery-powered instrumentation, and general analog signal processing. The wide supply range also permits operation from industrial 24 V systems when the total supply voltage remains within the device rating. Designers should account for input common-mode range, output swing, input bias current, and stable feedback-network selection when using the amplifier near its voltage limits. A key design consideration is the relationship between supply voltage, input range, and output swing. A nominal 3 V minimum supply does not mean the input and output can reach every rail voltage, so the signal amplitudes must remain inside the amplifier's specified common-mode and output ranges. Decoupling capacitors should be placed close to the supply pins, and feedback resistors should be selected to keep closed-loop gain and noise performance appropriate for the application. This product page combines the manufacturer's LM2902 product information, distributor references, package identification, and practical guidance for signal conditioning, supply bypassing, common-mode limits, and replacement planning.

Typical uses include four-channel sensor conditioning, precision threshold comparison, current-loop signal conditioning, industrial process-control interfaces, buffered instrumentation, and general embedded analog signal processing. In each case, the integrated quad topology reduces the number of amplifiers needed while retaining independent channel routing and common package-level supply handling. PCB design should preserve analog signal integrity by keeping input and output routing short, decoupling the supply pins close to the device, and avoiding current injection beneath the package. Confirm input common-mode range, output swing, supply limits, stability requirements, and channel-specific bandwidth needs against the manufacturer datasheet before finalizing the circuit. This page combines the Texas Instruments product description, exact-order MPN information, package details, verified source listings, and practical selection guidance.

The input-offset voltage is specified at 2 mV, while the maximum operating supply voltage is 26 V. These characteristics support moderate-bandwidth signal conditioning rather than high-speed precision applications. The LM2902 architecture provides internally frequency-compensated amplifiers, simplifying closed-loop use without an external compensation network. Each amplifier can operate as an inverter, non-inverting gain stage, comparator, buffer, or active filter element when operated within its common-mode and output-swing limits. The 14-lead TSSOP package provides a compact surface-mount format, but its narrow lead pitch requires careful PCB routing and adequate copper area for reliable assembly. Typical uses include industrial sensor interfaces, low-frequency active filters, control-loop error amplifiers, transducer signal conditioning, and four-channel instrumentation systems. Split-supply operation is useful when signals remain bipolar around ground, while single-supply operation fits battery-powered or process-control systems where a mid-supply reference can establish the signal center point. For reliable operation, verify the input common-mode range, output swing, supply current, and channel stability at the intended temperature before finalizing the PCB. Place bypass capacitors close to the supply pins, keep feedback components compact, and avoid routing sensitive input traces beside switching nodes or high-current output paths.

The wide supply-voltage capability is useful when the signal source operates from a higher rail than the system logic, while the common-mode input range including ground supports sensor interfaces whose signals remain near 0 V. The primary design consideration is supply bypassing and input/output stability. Place the required bypass capacitor close to the supply pins and route high-current return paths carefully to minimize ground displacement. Inputs must remain within the specified common-mode and absolute-maximum limits. Because the LM2902 is a general-purpose amplifier rather than a precision part, offset, bias current, output swing, noise, and slew-rate requirements should be checked against the actual signal chain before precision measurements are attempted. Use the manufacturer datasheet pin-description table and recommended application circuit when assigning PCB tracks.

Consult the manufacturer pin description and electrical characteristics before selecting external bias networks or designing for rail-to-rail behavior. The LM2902 uses a classic general-purpose four-amplifier architecture rather than rail-to-rail input or output stages. Consequently, common-mode and output-voltage limits depend on the selected supply voltage and load. Stable operation in unity-gain configurations should be confirmed against the manufacturer stability and load-capacitance guidance. Decoupling capacitors should be placed close to the supply pins to control supply impedance and maintain predictable transient behavior. Typical uses include automotive sensor interfaces, industrial control modules, battery-powered instrumentation, transducer amplifiers, and low-frequency active filters. The quad configuration reduces board area when four independent analog channels are required, while the high-voltage capability supports systems with a 24 V or 36 V supply architecture.

The 14-SO package is useful where designers want more integration than discrete single amplifiers while retaining a widely used surface-mount format. Its quad construction can reduce board area by consolidating four amplifier channels into one package. Each channel requires its own external feedback and compensation components determined by the circuit topology. Because the four channels share a package, designers should place input, output, power, and decoupling connections carefully to minimize coupling between high-impedance nodes and noisy output paths. Typical uses include conditioning sensor outputs in industrial equipment, buffering inputs to analog-to-digital converters, implementing active filters in audio and communications equipment, and closing control loops in power or measurement systems. The amplifier architecture is also appropriate for general-purpose educational and prototype boards requiring multiple independently configured channels. The primary design consideration is stable feedback. Each amplifier stage should use negative feedback and include compensation appropriate to the required gain and bandwidth. Input common-mode range, supply voltage, output swing, input offset voltage, and slew rate must be checked against the manufacturer datasheet before use, especially when operating near supply rails or driving capacitive loads. This page organizes the essential LM2902S14-13 package, application, and substitution information into an engineering-focused format.
