LM2901N - Quad Open-Collector Comparator | Texas Instruments
LM2901N

LM2901N - Quad Open-Collector Comparator | Texas Instruments

Texas Instruments LM2901N is a general-purpose quad differential comparator containing four independent comparator channels in a 14-pin through-hole DIP package. Each channel compares two input voltages and provides an open-collector output that can pull a logic node low or be released to a pull-up resistor. The device operates from a single supply or from split supplies, with a wide supply-voltage range extending to approximately 36 V. A comparator is a differential amplifier used to evaluate the relationship between two voltages. When the non-inverting input exceeds the inverting input, the associated output transistor turns on; reversing the inputs reverses the output state. The LM2901N belongs to the comparator hierarchy, which includes differential comparator ICs, analog interface ICs, and broader semiconductor signal-conditioning devices. Its four independent channels make it useful when a design requires multiple threshold, level, or sensing decisions. Important characteristics include a typical input bias current of 25 nA, typical input offset current of ±5.0 nA, and low supply-current consumption. The open-collector architecture is especially useful for wired logic, relay-driving interfaces, and systems that share a pull-up rail. Unlike a push-pull output, an open-collector output requires an external pull-up resistor and can safely combine multiple driver nodes when the device ratings and pull-up design are appropriate. The four channels share supply and ground pins but have independent inputs and outputs. This arrangement supports simultaneous comparisons, window detection, and complementary decision logic. Because the outputs are open collector, external pull-up resistors determine the high-state voltage and can be tied to TTL-, CMOS-, or MOS-compatible logic levels. The input arrangement permits sensing signals referenced to ground while the supply rail provides the comparator's operating voltage. Typical applications include industrial level detection, low-level sensing, consumer and automotive threshold decisions, memory and window-comparison circuits, and general-purpose control logic. The LM2901N is particularly appropriate when the design needs several channels, a wide supply range, low input bias current, and flexible output pull-up rather than rail-to-rail push-pull outputs. It is also useful in systems where output transistors must remain off until a wired-AND condition is satisfied. A key design consideration is the pull-up network. Select its resistance to balance rise time, output-sink current, power consumption, and the number of outputs connected to one node. Also route the four differential input pairs away from noisy supply and switching-current paths, because comparator input offset can determine the actual switching threshold. Confirm output-state behavior, input common-mode limits, and supply sequencing against the manufacturer datasheet before finalizing the circuit. This product page combines manufacturer information, distributor listings, package details, and practical comparator design guidance. It also identifies same-package alternatives and organizes the technical trade-offs for engineers comparing the LM2901N with other quad differential comparators before making a PCB-compatible sourcing decision.

LM2902AQS14-13

LM2902AQS14-13 - Quad 36V Automotive Op Amp | Diodes

Diodes Incorporated LM2902AQS14-13 is a four-circuit general-purpose operational amplifier designed for automotive-compliant applications, with a 3V to 36V single-supply range, a 20 nA input bias current, and a 14-pin SOIC package. The amplifier combines approximately 1 mV typical input offset voltage, 100 dB DC voltage gain, and 700 kHz unity-gain bandwidth in one package. An operational amplifier is a voltage-gain circuit that compares an inverting input with a non-inverting input and drives its output toward the difference between them. Operational amplifiers belong to the broader analog IC and signal-conditioning hierarchy. They are commonly used for sensor amplification, error amplification, voltage buffering, filtering, and analog-to-digital converter input conditioning. The LM2902 family is intended for general-purpose designs where four amplifiers and relatively wide supply-voltage tolerance provide more utility than a single precision amplifier. The principal electrical features include a 3V to 36V single-supply operating range, operation from ±1.5V to ±18V on dual supplies, and supply-current drain that is largely independent of supply voltage. Each amplifier supports rail-to-rail input operation, has a typical input bias current of 20 nA, and offers a typical open-loop DC gain of 100 dB. The temperature-compensated unity-gain bandwidth is 700 kHz, while the listed slew rate is 0.3 V/µs. The A-grade offset specification is 1 mV typical, making the device suitable for general signal-conditioning applications that do not require the tighter matching of a precision instrumentation amplifier. Internally compensated amplifiers simplify closed-loop gain selection, and the four independent channels can implement separate gain, filtering, comparison, buffering, or feedback functions. Their broad supply range also permits operation from industrial 24V supplies when designers observe the absolute maximum and common-mode limits. Typical uses include automotive sensor interfaces, industrial control loops, battery-powered instrumentation, transducer signal conditioning, low-current motor control, analog monitoring, and multichannel test equipment. The 14-pin SOIC footprint supports conventional surface-mount assembly and is useful when four channels must fit into one package. Common-mode and output-swing headroom should be checked against the actual signal and load because a wide supply rating does not mean the inputs and outputs can reach every supply rail under all conditions. A practical design starts by confirming the automotive-compliant variant requirement, power-supply range, input common-mode range, output swing, load capability, and noise-sensitive signal path. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs must be biased so they remain in a defined state. The SOIC package should be inspected for assembly-layout requirements and the complete operating limits in the manufacturer datasheet. This product overview combines the LM2902AQS14-13 electrical characteristics with package guidance, design considerations, and verified drop-in comparison options. It is intended to help engineers evaluate channel count, supply tolerance, offset performance, bandwidth, and automotive suitability before committing to a PCB design.

LM2902AT14-13

LM2902AT14-13 - Quad 1.3MHz Op Amp | Diodes Incorporated

Diodes Incorporated LM2902AT14-13 is a general-purpose quad operational amplifier containing four amplifier channels in a 14-pin TSSOP package. The device operates with a 1.3 MHz gain-bandwidth product, offers 100 dB open-loop gain, and draws 375 uA supply current per amplifier. Its four-channel integration makes it suitable for compact analog signal-conditioning boards requiring multiple independently configured amplifier stages. An operational amplifier, commonly called an op amp, is a high-gain differential amplifier used to amplify, filter, buffer, compare, or control analog signals. The LM2902 family belongs to the broader voltage-amplifier and analog-signal-processing hierarchy. It is intended for general-purpose designs rather than precision or high-speed signal chains, making it useful for transducers, sensor interfaces, audio paths, and control systems where economy, low power, and functional integration are priorities. The quad configuration provides four amplifiers in one package, reducing board area compared with four separate single or dual amplifier packages. The 1.3 MHz gain-bandwidth product supports applications requiring moderate rather than very high closed-loop bandwidth. Its 100 dB open-loop gain provides substantial correction capability, while the 375 uA operating current per channel supports low-power analog systems. Operating from a single supply is useful when negative supply rails are unavailable or undesirable. The LM2902 uses a conventional general-purpose amplifier architecture intended for moderate accuracy and broad operating conditions. Because the four channels share one package, their supply, ground, and thermal environments are closely related. Designers should preserve adequate stability around each amplifier, account for input common-mode range and output swing, and avoid relying on rail-to-rail input or output operation. The 1.3 MHz bandwidth also makes stability and noise considerations more important than in precision, low-offset alternatives. Typical uses include four-channel sensor conditioning, low-frequency active filtering, audio preamplification, comparator-style threshold circuits, current-to-voltage conversion, and general industrial control. The package is particularly useful when several low-frequency analog channels must be consolidated on a compact board. Its automotive temperature grade makes it relevant to vehicle electronics, provided each electrical limit is evaluated against the complete operating environment. A primary design consideration is the voltage-loss margin required by a non-rail-to-rail amplifier. Input and output voltage ranges must be checked against the actual supply voltage and signal amplitude. Decoupling should be placed close to the supply pins, the unused amplifier channel should be configured according to the manufacturer's recommendations, and PCB grounding should minimize voltage-drop and feedback coupling between sensitive channels. This product record combines the LM2902AT14-13 specifications with package guidance, application-oriented design notes, and a strict compatibility review. It helps engineers determine whether the quad TSSOP implementation fits a power-conscious analog design before committing to a board layout or production release.

Its differential input structure makes it useful for amplifying sensor signals, buffering analog voltages, and implementing general-purpose analog signal-conditioning circuits. Key operating characteristics include a 1 MHz gain-bandwidth product and 0.6 V/µs slew rate. The 3 V minimum supply voltage supports low-voltage analog systems, while operation up to 32 V covers higher-voltage industrial signal chains. Four independent channels reduce package count and simplify board design when multiple analog signals must be amplified, buffered, or filtered. The LM2902 family uses the LM324-series architecture optimized for single-supply operation. True differential inputs allow each amplifier to respond to the voltage difference between its inverting and non-inverting terminals.

Typical uses include industrial sensor interfaces, low-side current measurement, analog signal conditioning, transducer amplification, general-purpose buffer stages, and four-channel control systems. A single package can implement four similar signal paths, provided each channel remains within its input-voltage, output-swing, current, and stability limits. A key design consideration is the relationship between supply voltage, output swing, and input common-mode range. Confirm that incoming sensor signals remain within the amplifier's permitted input range and that the required output voltage can be reached with the selected load. Place bypass capacitors close to the supply pins and route the common ground connection carefully to minimize offset and noise coupling. This product page combines the exact LM2902DG electrical and package identifiers with engineering-focused selection guidance, drop-in cross-reference information, comparison parameters, and practical PCB design notes.

LM2902DG4

LM2902DG4 - Quad 1.2MHz Op Amp, 26V | Texas Instruments

Texas Instruments LM2902DG4 is a general-purpose quadruple operational amplifier packaged in a 14-pin SOIC tube. Each of its four independent amplifier sections has a gain-bandwidth product of 1.2 MHz and a slew rate of 0.5 V/µs. The device supports single-supply operation up to 26 V and split-supply operation up to ±13 V, with an input offset voltage of 2 mV. Its four-amplifier configuration consolidates multiple analog signal-conditioning channels into one package. A general-purpose operational amplifier is an analog IC that amplifies the voltage difference between its non-inverting and inverting inputs. The LM2902 belongs to the operational-amplifier hierarchy, which includes instrumentation, comparator, voltage-feedback, and current-feedback devices. Four independent sections allow a single LM2902DG4 to implement functions such as sensing, buffering, error amplification, active filtering, and output-current buffering when their common-mode, voltage, and timing requirements overlap. The LM2902's principal characteristics include four amplifier circuits, a 1.2 MHz gain-bandwidth product, a 0.5 V/µs slew rate, and a typical supply-current drain of 0.8 mA. Its input offset voltage is specified as 2 mV, while the operating supply range extends to 26 V on a single supply or ±13 V from a split supply. These characteristics make the device appropriate for general-purpose industrial control, analog signal conditioning, and low-to-moderate-frequency closed-loop applications. The LM2902 is designed around four internally compensated, high-gain operational-amplifier sections. Its 1.2 MHz gain-bandwidth product limits the closed-loop bandwidth achievable at a given noise gain, while the 0.5 V/µs slew rate governs large-signal response. Because all four sections share the same package and supply pins, layout should preserve short feedback paths and provide suitable supply bypassing close to the device. Typical uses include transducer-signal conditioning, low-frequency active filters, industrial sensor interfaces, control-loop error amplifiers, and analog signal buffers. A single package is particularly useful when a board needs several similar amplifier channels and designers want to reduce component count. For applications requiring precision offsets, wider bandwidth, lower noise, rail-to-rail inputs or outputs, or automotive qualification, the design should use a more specialized amplifier rather than assume the LM2902 provides those capabilities. When laying out a board, place the bypass capacitor at the supply pins and route feedback components close to the relevant amplifier section. Check input and output swing against the actual load because the usable signal range depends on the supply voltage and output-load conditions. For stable operation, confirm that the intended noise gain and closed-loop gain are compatible with the 1.2 MHz gain-bandwidth product and that the resulting output slew requirement remains below 0.5 V/µs. This page organizes the LM2902DG4 specifications, pinout, practical design guidance, application examples, and verified drop-in alternatives into one engineering reference. It also separates core device characteristics from procurement details so designers can evaluate the amplifier's package, supply range, bandwidth, and replacement options before committing it to a PCB design.

LM2902DR2 - Quad Single-Supply Op Amp | onsemi | SOIC-14

The onsemi LM2902DR2 is a single-supply, quad operational amplifier packaged in a 14-pin SOIC. It integrates four independent amplifiers in the LM2902 family, combining differential inputs, low input offset voltage, and a high gain-bandwidth product for general-purpose analog signal conditioning. The LM2902 family supports supply voltages up to 36 V and can also operate from split supplies when supported by the device operating conditions. Its four-amplifier arrangement reduces package count and simplifies board layout where multiple analog channels are required. An operational amplifier is a high-gain, frequency-compensated analog building block used to amplify differential signals, buffer inputs, compare voltages, and drive feedback-control networks. The LM2902 belongs to the broader hierarchy of operational amplifier, analog amplifier IC, signal-conditioning IC, and power-management semiconductor. Its differential-input architecture requires the two input voltages to be considered together, while its common-mode input range can extend to ground for many single-supply applications. The principal benefits of the LM2902DR2 are its four integrated channels, 36 V supply capability, low input offset voltage, and high gain-bandwidth product. Four independent amplifiers in one 14-pin package simplify designs that require several matched circuit functions, such as sensor conditioning, active filtering, or control-loop sections. The low offset voltage helps reduce output error when the amplifier is used with negative feedback, although the actual error also depends on input bias current, resistor matching, temperature, and common-mode operating conditions. The LM2902DR2 is part of the established LM324-family class of low-cost, single-supply quad operational amplifiers with true differential inputs. Because the device is frequency compensated, designers can create stable closed-loop gain stages without adding external compensation capacitors in typical applications. Its 14-pin SOIC footprint supports conventional surface-mount assembly and is also convenient for prototypes, hobbyist boards, education kits, and repair platforms that use the standard quad-op-amp outline. Typical uses include industrial sensor interfaces, low-frequency audio amplification, active filters, comparator-style signal conditioning, and general instrumentation. The quad organization is particularly useful when a circuit needs two or more gain stages, an amplifier-based filter, or multiple independent analog channels. For power-sensitive systems, the 36 V operating class also allows the device to sit behind higher-voltage supplies when the application and protection requirements permit it. When designing a board around the LM2902DR2, check supply voltage, common-mode range, output swing, input bias current, and the required closed-loop gain at the operating frequency. Place input and feedback components close to the relevant amplifier pins, and keep sensitive input nodes away from switching-current paths. Decouple each supply rail near the device, and confirm that every connected output remains within its valid output-voltage range under worst-case load and temperature conditions. This product page combines the LM2902DR2 technical description, package details, sourcing workflow, application guidance, and verified drop-in alternatives. It also organizes parameter comparisons and practical PCB considerations so engineers can evaluate the device, its replacements, and its role in a complete analog signal chain before releasing a design.

The device contains four amplifiers in a 14-pin SOIC package, making it suitable for instrumentation, buffering, signal conditioning, and general analog signal-processing circuits. Its integrated design allows four amplifier channels to be placed in one compact package while supporting common single-supply architectures. A general-purpose operational amplifier is a voltage-amplifying active device that uses differential inputs and feedback to control gain, filtering, buffering, and signal conditioning. The quad LM2902 family combines four amplifiers within one semiconductor package, reducing board area and simplifying designs that require multiple independent analog channels. The LM2902DR2G is associated with the onsemi LM2902 family and is identified by distributor listings as a single-supply quad operational amplifier in a 14-SOIC package. The key device characteristics are the four-amplifier configuration, 3 V to 26 V supply range, 14-SOIC package, and general-purpose single-supply operation. These specifications make the device suitable for industrial control systems, sensor interfaces, low-frequency signal conditioning, audio and communications support circuits, and general instrumentation. Because the LM2902 is a general-purpose amplifier rather than a precision or high-speed part, designers should verify input bias current, output swing, noise, slew rate, and stability requirements against the manufacturer datasheet for the actual operating conditions. In a typical single-supply design, the LM2902 is powered from a positive supply while the signal source and reference point are biased near ground. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs should be biased so that they remain in a defined operating state. Feedback-network values determine gain and bandwidth, so resistor and capacitor tolerances directly influence signal accuracy. The device should also be evaluated for output-current capability and thermal rise when driving capacitive loads or operating at elevated temperatures. Common uses include sensor signal conditioning, low-level instrumentation, control-loop input stages, active filtering, waveform conditioning, and general-purpose buffering. The 14-SOIC package provides a familiar footprint for designs using standard through-hole assembly, although the exposed thermal behavior and electrical limits remain important at higher ambient temperatures. The LM2902DR2G is therefore best suited to cost-sensitive, low-to-moderate-frequency analog systems where four channels and single-supply convenience matter more than precision or high bandwidth. This page summarizes the device identity, package, operating range, sourcing information, drop-in alternatives, application guidance, and engineering considerations for engineers evaluating LM2902DR2G. The manufacturer datasheet should be consulted for the complete electrical characteristics, recommended operating conditions, pinout, and application details before final circuit release.

The Texas Instruments LM2902DRG3 is a general-purpose quadruple operational amplifier with four independent amplifiers, a 26 V maximum supply rating, 1.2 MHz gain-bandwidth product, and 2 mV input offset voltage in a 14-pin SOIC package. The LM2902DRG3 suffix denotes a tape-and-reel shipping configuration. An operational amplifier, or op amp, is a high-gain analog signal-processing component used to amplify voltage differences, buffer sensors, drive analog inputs, and implement feedback-control circuits. The LM2902 belongs to the quad operational-amplifier family within the broader voltage-amplifier and analog-signal-processing semiconductor hierarchy. Its four amplifiers share power-supply pins but have independent input and output connections, allowing one package to implement four related analog functions. The LM2902 operates from single or split supplies over a wide voltage range, making it useful in industrial-control, instrumentation, and audio circuits. Key characteristics include a 1.2 MHz gain-bandwidth product, 0.5 V/µs slew rate, and approximately 0.8 mA typical supply-current drain. Four frequency-compensated amplifiers support common closed-loop configurations including noninverting and inverting gain, voltage followers, comparators, summing amplifiers, and difference stages. Its 14-pin SOIC package provides a familiar industrial footprint and thermal performance suitable for conventional through-hole assembly workflows. Because each channel is independent, the IC can implement sensor conditioning, signal amplification, active filtering, and control-loop functions on one board. Single-supply operation simplifies designs where the signal remains above ground, while split-supply operation supports bipolar signals centered around zero volts. Typical applications include industrial sensor interfaces, transducers, audio preamplifiers, analog-to-digital converter input conditioning, motor-control support circuits, and general-purpose instrumentation. The wide supply range and low supply-current drain make the device practical in equipment powered from industrial rails or split supplies, provided the absolute maximum operating limits remain respected. Designers should verify input and output common-mode limits for each supply configuration, account for the offset voltage when precision is important, and use stable feedback networks for unity-gain or noise-sensitive applications. PCB placement should keep sensitive input nodes compact, provide an appropriate ground-return path, and avoid placing high-current switching paths close to amplifier inputs. This product page combines the LM2902 family specifications, package information, sourcing guidance, verified drop-in candidates, application examples, and practical design considerations. The comparisons also distinguish package-compatible alternatives from choices that require different qualification, temperature-range, or performance checks before substitution.

Texas Instruments LM2902DRG4 is a four-channel operational amplifier with a 26 V maximum supply rating, 1.2 MHz gain-bandwidth product, and 2 mV input-offset specification in a 14-pin SOIC package. Designed for general-purpose signal conditioning, each amplifier can operate from single or dual supplies, supporting a broad range of industrial, instrumentation, control, and analog-interface applications. An operational amplifier is an analog integrated circuit that uses differential feedback to amplify the difference between two input voltages. The LM2902 belongs to the operational-amplifier hierarchy, where it combines transistor-level input and output stages with internal compensation. Each of its four channels can perform amplification, buffering, comparison, summation, differential sensing, or active-filter functions without requiring a separate amplifier for every signal path. The device provides a 1.2 MHz gain-bandwidth product and a 2 mV input-offset specification, making it suitable for moderate-bandwidth precision applications. The 26 V supply capability also supports higher-voltage industrial interfaces than low-voltage rail-to-rail amplifiers. Texas Instruments specifies an operating temperature range from -40°C to 125°C, allowing operation across demanding commercial and industrial environments. The four amplifiers share one package while retaining independent input and output pins, allowing one IC to implement several analog functions. Their typical design role is to operate with feedback networks that establish closed-loop gain and filtering. Because the device is not rail-to-rail by specification, input and output common-mode limits must be checked against the selected supply voltage and signal range before layout release. Typical uses include transducer signal conditioning, low-frequency active filters, sensor amplifiers, industrial control loops, comparator-style threshold circuits, and audio or communications interface stages. The SOIC package also simplifies inspection and rework on through-hole industrial boards while providing a familiar 14-pin land pattern. For a new design, verify the input and output common-mode range, output-current capability, load impedance, and supply operating limits at the intended signal amplitude. Stable feedback and proper decoupling remain important even when the application is a unity-gain buffer, so use the manufacturer pin-description table when assigning PCB tracks. This page organizes the LM2902DRG4 specifications, verified manufacturer references, same-package alternatives, application guidance, and comparison points. It also highlights the practical checks needed to determine whether a candidate replacement is truly pin-compatible rather than merely functionally similar.

LM2902EDR2G

LM2902EDR2G - Quad Single-Supply Op Amp, 14-SOIC | onsemi

The onsemi LM2902EDR2G is a single-supply quad operational amplifier that integrates four independent, general-purpose amplifiers into a 14-pin SOIC (PDSO-14) surface-mount package, with input offset voltage specified up to 7000 uV. It is designed for general-purpose signal conditioning, filtering and control tasks on low-voltage rails. A quad operational amplifier is a multi-channel analog building block in which four voltage amplifiers share a common package and power supply. Each channel offers inverting and non-inverting inputs and a single output. The quad configuration lets one part provide four amplifier functions - instrumentation gain stages, active filters, comparators, level shifters or buffer stages - while cutting board area, reducing the number of supply pins and lowering per-channel cost. In the analog signal chain, a quad op amp sits between sensors and converters, inside the family of amplifier ICs and linear analog ICs. Key characteristics of the LM2902EDR2G include four amplifier circuits in one package, a maximum input offset voltage of 7000 uV, single-supply operation, and a low-power general-purpose architecture suited to instrumentation and control designs. The 14-pin SOIC footprint is a widely supported package with good thermal performance, adequate creepage and clearance for 36 V-class class parts, and compatibility with automated assembly and standard SOIC sockets. Internally, the device uses the classic bipolar single-supply topology that has made the LM2902 family a long-lived industry standard: a differential input stage driving a push-pull output stage, with internal compensation that allows stable operation as a unity-gain buffer. Because it is a general-purpose amplifier rather than a precision or rail-to-rail part, the design engineer should treat the input common-mode range, output swing and offset as application-dependent limits rather than rail-to-rail capabilities. Typical applications include transducer and sensor signal conditioning, active low-pass and band-pass filters, motor and actuator control loops, audio pre-amplification in consumer equipment, 4-20 mA loop instrumentation, and general microcontroller analog front ends where a quad amplifier saves board space. When designing around this device, confirm the common-mode input range and output swing against your actual supply voltage, and keep the layout symmetrical so that thermal gradients do not create offset mismatch between the four channels. Decouple each supply pin locally with a short, low-inductance path to the ground plane, and route feedback components away from noisy digital return paths. This page brings together the manufacturer datasheet details, a qualified drop-in alternative set with verified package compatibility, and application-specific design notes that go beyond the parameter table.

The automotive-qualified LM2902-Q1 family is designed for systems requiring four amplifiers per package, extended-temperature operation, and reliable operation across a wide supply range. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its non-inverting and inverting inputs. The LM2902 contains four independent, internally compensated amplifiers, allowing one package to provide feedback control, buffering, signal conditioning, or differential-to-single-ended conversion. In the power-management hierarchy, it is an analog signal-chain IC rather than a voltage regulator, although its wide supply tolerance makes it useful in industrial and automotive power systems. The headline specifications include four amplifier circuits, a 1.2 MHz gain-bandwidth product, a 0.5 V/us slew rate, and approximately 2 mV offset voltage. The device also provides a typical common-mode rejection ratio of 80 dB and an input bias current of 20 nA. Its 30 V operating capability suits 12 V automotive systems, industrial control equipment, audio electronics, and instrumentation while allowing operation from lower single-supply voltages. Each amplifier is frequency compensated and optimized for general-purpose analog design rather than high-speed differential signaling. A 1.2 MHz gain-bandwidth product is most useful at moderate closed-loop gains, while the 0.5 V/us slew rate limits large-signal response at low frequencies. The four independent channels can be configured independently for noninverting, inverting, comparator-like, summing, and feedback-amplifier circuits, subject to common-mode and output-swing limitations. Typical uses include automotive sensor interfaces, battery-powered monitoring equipment, active filters, audio preamplifiers, industrial transducers, and general-purpose control loops. Four amplifiers in one SOIC-14 package reduce board area and component count when several low-frequency analog channels are required. The automotive qualification makes the LM2902-Q1 family especially suitable for body electronics, actuator interfaces, and vehicle sensing systems. Design with the supply voltage, input common-mode range, output swing, input bias current, and capacitive-load drive in mind. Decoupling capacitors should be placed close to the supply pins, and sensitive input traces should be kept away from switching nodes. Because the gain-bandwidth and slew-rate limits are modest, verify stability with the intended feedback network and load capacitance before scaling the design into production. This page combines manufacturer specifications, lifecycle information, application guidance, and same-footprint alternatives. It also provides practical design notes and parameter comparisons that help engineers distinguish functionally similar LM2902 variants and choose a suitable replacement without assuming that every ordering code is electrically identical.

The LM2902 supply arrangement supports 26 V single-supply operation or plus-and-minus 13 V dual-supply operation. Supply-current drain is specified as low as 0.8 mA typical and remains independent of supply voltage. The common-mode input voltage range includes ground, making the amplifier suitable for single-supply sensors whose outputs remain near 0 V. Differential input voltage capability and rail-to-rail output behavior also make the device useful in cost-sensitive analog signal chains where the output must approach supply limits. The B-generation device is positioned by Texas Instruments as a drop-in replacement for LM224, LM324, and LM2902 versions with improved specifications. Typical uses include industrial sensor conditioning, transducer amplification, low-frequency active filters, instrumentation amplifiers, audio preamplifier stages, motor-feedback networks, and general-purpose power-control loops. Four amplifiers can implement a complete low-speed control or measurement chain in a single package. PCB design should prioritize short feedback traces, clean grounding, and input-node protection from switching or high-energy sources. Decoupling capacitors should be placed close to the supply pins, and unused amplifier channels should be tied to a defined common-mode voltage rather than left floating. The 14-TSSOP package uses a narrow lead pitch, so inspect the manufacturer land pattern and solder reflow profile before assembly.

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.

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.

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 automotive qualification makes it suitable for electronic control units, body systems, instrumentation, and other 12 V vehicle platforms where operating-temperature robustness and supply-voltage tolerance are important. The device combines a 1.2 MHz gain-bandwidth product with a typical slew rate of 0.5 V/µs and a common-mode rejection ratio of 80 dB. 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.

Typical uses include industrial sensor interfaces, transducer signal conditioning, low-frequency active filters, analog summing amplifiers, instrumentation buffers, and general control-system analog channels. Because four amplifiers are integrated in one package, it can also reduce component count in multi-channel sensor, monitoring, and data-acquisition designs where channel-to-channel consistency and compact implementation are beneficial. Designers should account for input common-mode range, output swing, supply headroom, stability with the selected feedback network, input bias current, and the effects of capacitive loading. Decoupling capacitors should be placed close to the supply pins, and sensitive inputs should be routed away from high-current switching nodes. The TSSOP package requires careful assembly practices because its fine lead pitch can increase solder-bridging risk. This product page combines the manufacturer specifications, package details, application guidance, and qualified drop-in comparisons to simplify component selection. It also highlights the distinctions between the original LM2902 variants and the improved LM2902KV device, helping engineers confirm compatibility before changing an existing 14-pin TSSOP design.

LM2902KVQPWRQ1 - 26V Quad 1.2MHz Automotive Op Amp | TI

The Texas Instruments LM2902KVQPWRQ1 is a four-circuit general-purpose operational amplifier qualified for automotive applications, with a 26 V maximum supply rating, 1.2 MHz gain-bandwidth product, and 2 mV offset voltage. It is housed in a 14-pin TSSOP package and is intended for applications requiring multiple independent high-voltage amplifier channels in one compact device. The LM2902-Q1 family is qualified according to AEC-Q100 specifications, while the LM2902B-Q1 and LM2902BA-Q1 members are described as next-generation versions with improved high-voltage operation. An operational amplifier, or op amp, is a voltage-controlled differential amplifier with very high open-loop gain. It compares two input voltages and drives its output toward the difference between them. Because the LM2902KVQPWRQ1 contains four independent, frequency-compensated amplifiers, one package can provide input buffering, sensor conditioning, voltage amplification, current sensing, and active filtering without requiring four separate devices. It supports single-supply operation and split-supply operation, subject to the device’s stated supply limits. The principal advantages of this device are its high-voltage capability, automotive qualification, integrated four-channel architecture, and broad applicability in industrial and vehicle electronics. The 1.2 MHz bandwidth supports general-purpose signal conditioning rather than high-speed precision analog work. Its 2 mV input offset voltage is useful for applications where the input signal is sufficiently large to keep offset errors below the required accuracy. The four channels also allow consistent amplifier performance across multiple signal paths in the same system. Typical applications include 12 V and 24 V automotive sensor interfaces, battery monitoring, pressure and temperature signal conditioning, current sensing, motor-control feedback networks, industrial control modules, and instrumentation buffers. The 14-pin TSSOP package is compact and suitable for high-density PCB layouts, but automotive designs should account for copper-area limitations, thermal dissipation, transient protection, and the need to keep sensitive input traces away from switching and power-conversion nodes. When selecting a replacement, verify the exact channel count, package, supply rating, offset voltage, bandwidth, common-mode behavior, output-drive capability, automotive qualification, and operating-temperature grade. The LM2902KVQPWRQ1 is best suited to four-channel, general-purpose automotive and industrial designs where 26 V operation and AEC-Q100 qualification are more important than high precision or high speed. This page combines the manufacturer product information with practical comparison, replacement, and design guidance for engineers evaluating the device in an existing circuit.
