LM258YPT

LM258YPT - Dual Low-Power Op Amp | STMicroelectronics

The STMicroelectronics LM258YPT is a low-power dual operational amplifier consisting of two independent, high-gain, internally frequency-compensated amplifiers in an 8-pin TSSOP package. According to the manufacturer product page, the device is designed for single-supply operation over a wide voltage range, while the distributor listing identifies a 100 dB gain specification and 1.1 MHz bandwidth. Each amplifier includes low-input-bias-current characteristics suited to feedback, sensing, and signal-conditioning circuits. An operational amplifier is a high-gain analog building block that compares two input voltages and drives its output toward the difference between them. The LM258 belongs to the dual operational-amplifier family within the broader linear IC and amplifier hierarchy. Internally frequency compensation simplifies closed-loop use because designers do not need to add an external dominant-pole capacitor for ordinary stable operation. The LM258YPT provides two amplifiers in one compact surface-mount package. Its 100 dB gain and 1.1 MHz bandwidth make it appropriate for audio-frequency signal paths, transducer conditioning, feedback networks, and low-frequency control applications. Low input bias current helps preserve measurement accuracy when the source impedance is relatively high, while the dual configuration saves board area compared with two separate single amplifiers. Each channel is independent, allowing one section to perform amplification while the other handles a different signal or a supervisory function. Because the amplifiers can operate from a single supply, the output range remains constrained by the supply rails. Designers must account for this limitation in rail-to-rail sensing applications or add suitable biasing when signals extend below the lower supply voltage. Typical uses include audio preamplification, temperature-sensor interfaces, light-control loops, low-level instrumentation, and general feedback-control systems. The 8-pin TSSOP package is useful for compact industrial, instrumentation, and embedded-control designs where two amplifiers are required but a through-hole dual operational amplifier would be unnecessarily large. Layout should keep feedback components close to the relevant input and output pins, maintain a continuous ground reference, and place decoupling capacitance near the supply pins. Input and output nodes should remain short to reduce parasitic pickup. Designers should also verify common-mode range, output swing, slew rate, supply voltage, stability, and load behavior against the manufacturer datasheet before finalizing the circuit. This product page combines manufacturer-device identification, distributor availability information, pinout and datasheet references, application guidance, and qualified same-package alternatives. It is structured to help engineers compare the LM258YPT against other 8-pin dual operational amplifiers without treating every functionally similar device as a true drop-in replacement.

LM2893M

LM2893M - 4.8 kBaud FSK Power-Line Transceiver | Texas Instruments

The Texas Instruments LM2893M is a carrier-current transceiver integrated circuit for half-duplex serial data communication over existing power lines. It combines an FSK transmitter, a receiver with phase-locked-loop demodulation, and an interface to the carrier-current network in a 20-terminal SOP package. The verified device supports data rates up to 4.8 kBaud and an operating temperature range of -40°C to +85°C. A carrier-current transceiver is a communications interface that superimposes a modulated signal onto an electrical power or communication line. In the broader electronics hierarchy, this device belongs to the interface-IC category rather than a general-purpose data converter. The LM2893M is designed to communicate short serial messages between remotely distributed nodes without requiring a dedicated signal pair, making it useful for energy-management equipment, home-automation controllers, appliance control, and industrial systems that already share a mains-powered network. The principal verified features include FSK modulation, phase-locked-loop demodulation, half-duplex bidirectional operation, a maximum data rate of 4.8 kBaud, operation from an 18 V supply, and a -40°C to +85°C industrial temperature range. Its 20-terminal gull-wing SOP package has a 1.27 mm terminal pitch according to the verified distributor listing. Because carrier-current communication is sensitive to network loading, coupling method, attenuation, noise, and grounding, successful implementation requires the interface network and filtering to be evaluated with the intended power-line environment. The LM2893M is most appropriate when both ends of a link can share a power or utility line and low data throughput is sufficient. The 4.8 kBaud rate suits status reporting, control commands, meter-reading messages, and energy-management telemetry rather than streaming data. Half-duplex operation requires the controller to avoid simultaneous transmission and to manage turnaround timing, while the PLL-based receiver provides the demodulation function required to recover FSK information from the carrier waveform. Designers should provide suitable supply bypassing and define the line-coupling, protection, filtering, and grounding arrangement with the actual mains network. Regulatory, safety, and isolation requirements must be handled by the complete interface circuit rather than assumed to be satisfied by the IC. The LM2893M itself is not a mains-isolated network interface, and its operating voltage should not be confused with the voltage appearing on the coupled power line. This page combines verified pricing, package information, operating limits, interface characteristics, and application guidance with the available manufacturer-family relationship. It also documents the absence of verified drop-in equivalents instead of presenting unverified substitutes as production-ready replacements.

LM2893N

LM2893N - Carrier-Current Transceiver | National Semiconductor

National Semiconductor LM2893N is a one-transceiver carrier-current interface IC designed for half-duplex, bidirectional serial communication over an existing power-mains network. The device is offered in a 20-pin PDIP package and combines a transmitter and receiver in one integrated circuit. Carrier-current systems use power-line infrastructure to transfer information between remotely separated locations rather than requiring a separate communication cable. A carrier-current transceiver is a type of power-line interface IC. Carrier-current communication belongs to the broader power-line networking and interface IC hierarchy, where communication signals are superimposed on an electrical power conductor. The LM2893N is intended to interface a serial data source with a carrier-current network, making it useful where the mains wiring already extends between remote nodes and adding a separate low-speed communication route would be impractical. The verified source information identifies the LM2893N as a one-transceiver, 20-PDIP device for carrier-current systems. Its principal benefit is integration: both directions of the half-duplex link are handled by a single package instead of separate transmitter and receiver packages. The confirmed communication mode is bidirectional and serial, allowing a node to exchange bit-stream data with another node over the same carrier-current medium. The LM2893N belongs to the bipolar LM1893/LM2893 carrier-current transceiver family. This family positioning indicates that the LM2893 is the higher-temperature-oriented member relative to the LM1893 designation, although exact electrical limits and comparison values are not included in the supplied distributor data. Designers should use the manufacturer datasheet for voltage ratings, current limits, logic thresholds, transmission timing, receiver sensitivity, and network-interface details before releasing production hardware. Typical carrier-current uses include remote metering, building-management communication, industrial monitoring, appliance control, and low-speed supervisory links where power and data share the same wiring. In these systems, the LM2893N acts as the physical-layer interface between the communication network and the node's serial logic. Network loading, isolation requirements, coupling method, transmit power, and protocol timing remain application-specific. The principal design consideration is that carrier-current communication is materially different from ordinary RS-485 or isolated digital communication. The power conductor presents a difficult noise environment, and the interface network must be characterized for attenuation, impedance, coupling, and surge exposure. PCB grounding, filtering, isolation boundaries, and protection components therefore deserve attention before the communication protocol is finalized. This product page combines verified distributor identification, family-level technical context, package information, sourcing links, and structured engineering guidance that is not available in a basic distributor listing. Exact electrical specifications and qualified drop-in replacements remain explicitly separated from verified facts so engineers can make a safe replacement decision without relying on assumptions.

LM2900N - Quad 2.5MHz Norton Operational Amplifier | TI

The Texas Instruments LM2900N is a quad, high-gain, frequency-compensated Norton operational amplifier with four independent amplifiers in a 14-pin PDIP package. Its headline specifications include a 2.5 MHz gain-bandwidth product, 20 V/µs slew rate, 4.5 V to 32 V single-supply operation, and ±2.2 V to ±16 V dual-supply operation. An operational amplifier is an analog signal-conditioning IC that uses high open-loop gain to amplify the difference between two input voltages. The LM2900 belongs to the Norton-operational-amplifier family, characterized by current-feedback-style input stages. Within the broader electronics hierarchy, it is an analog amplifier IC, then an operational amplifier, then a general-purpose quad amplifier. The LM2900 provides four independent amplifiers, wide bandwidth, large output-voltage swing, short-circuit protection, internal frequency compensation, and low input-bias current. Internal compensation removes the need for external compensation components in ordinary closed-loop operation, simplifying analog boards that need several amplified signals on one supply rail. Its specified 4.5 V to 32 V single-supply range makes it applicable to legacy industrial control, instrumentation, sensor interfaces, audio, and communications equipment. The 20 V/µs slew rate supports faster edge rates than many general-purpose amplifier selections, while the 2.5 MHz bandwidth gives useful signal bandwidth for audio and control applications. The DIP package also supports through-hole assembly and socketed prototypes. When designing around the LM2900N, verify input and output common-mode limits at the selected supply voltage. Account for the input-bias current when driving high-impedance sensors, and use stable feedback networks with resistive isolation where required by the source impedance. The device uses four independent amplifiers, but shared-package power and ground connections still require careful layout.

LM2901D

LM2901D - 30V Quad Differential Comparator | Texas Instruments

The Texas Instruments LM2901D is a 30 V quad differential comparator containing four independent open-collector comparator channels in a 14-pin SOIC package. Each channel supports single or split-supply operation, while the device is designed for level detection, low-level sensing, memory, consumer, automotive, and industrial applications. The LM2901D combines a typical input bias current of 25 nA with a typical input offset current of ±5 nA. A comparator is an analog integrated circuit that evaluates two input voltages and produces a logic-level result indicating which input is higher. Within the semiconductor hierarchy, the LM2901D is a voltage comparator, a linear signal-conditioning IC commonly grouped with amplifier and interface functions. Its open-collector outputs require an external pull-up resistor, allowing several outputs to be wired together when the resulting wired-AND behavior is appropriate for the system. The four independent channels make the LM2901D useful where several sensing decisions must be made in one package. Its open-collector output structure can drive TTL, CMOS, MOS, DTL, and ECL-compatible logic as identified in the manufacturer literature. The specified 300 ns response time supports general-purpose detection rather than the latency demanded by high-speed timing applications. Split-supply operation also permits bipolar sensing around a zero-volt reference. The input stage emphasizes low bias current, which reduces disturbance of high-impedance sensor outputs. A typical 25 nA input bias current is suitable for many threshold and level-detection circuits, while the typical ±5 nA input offset current helps minimize imbalance between the differential inputs. These characteristics should be considered together with input common-mode limits, output pull-up requirements, and supply-voltage tolerances during design verification. Typical uses include monitoring battery or power rails, detecting overvoltage and undervoltage conditions, comparing sensor thresholds, implementing window comparators, and providing four-channel status indication. Because all four outputs are open collector, a pull-up resistor is normally required on each channel. Connecting multiple open-collector outputs to one pull-up can reduce the number of logic signals, but it also creates a shared fault domain and requires careful analysis of output leakage and pull-up current. A practical design must preserve adequate input common-mode headroom at both supply rails, keep differential input voltage within the absolute maximum limits, and select pull-up resistors for the voltage and sink-current requirements of the connected logic. Decoupling capacitors should be placed close to the supply pins, while unused comparator inputs should be tied to a defined potential rather than left floating. This page organizes the key LM2901D electrical characteristics, manufacturer-backed comparison options, pin-package constraints, and application guidance for engineers evaluating a 14-pin quad comparator. It also highlights the practical trade-offs involved when selecting a drop-in alternative with different input offset, bias current, temperature range, or propagation timing.

LM2901M

LM2901M - 4-Channel 36V Open-Collector Comparator | Texas Instruments

Texas Instruments LM2901M is a four-channel differential analog comparator with an operating supply range of 2 V to 36 V, a typical response time of 1.3 µs, and open-collector outputs in a 14-pin SOIC package. Designed for single-supply operation, it can also operate from dual supplies providing approximately ±1 V to ±18 V. Each comparator compares two input voltages and produces a digital result that can drive TTL, MOS, or CMOS-compatible logic. The package is identified by the M suffix and is suitable for conventional through-hole PCB assembly when surface-mount assembly is not required. An analog comparator is a semiconductor that converts the relationship between two voltages into a logic-level output. The LM2901 belongs to the comparator hierarchy, where a general-purpose comparator is used for threshold detection, signal conditioning, and industrial control rather than precision analog amplification. Its wide supply range, low input bias current, and low typical supply-current consumption make it suitable for systems operating from low-voltage control circuits through higher-voltage industrial environments. The principal features include four independent comparator channels, an approximate 36 V maximum supply, 800 µA typical supply-current drain, 25 nA typical input bias current, and open-collector outputs suitable for wired logic. These characteristics allow the device to monitor slow and fast control signals while maintaining low loading on high-impedance sensor nodes. The open-collector architecture also supports wired-AND behavior when multiple comparators share a pull-up resistor, although the common output node requires careful voltage and timing analysis. Each internal comparator has an inverting input, a non-inverting input, and an open-collector output. The open-collector transistor normally remains off, so an external pull-up resistor is required to establish a high output state. When the comparator output is pulled low, the output transistor sinks current from that pull-up network. The resulting interface can support wired logic, relay-driver stages, lamp indicators, and other systems where a pulled-up bus must be shared safely. Typical applications include industrial sensor-limit detection, overvoltage and undervoltage monitoring, battery threshold detection, control-system interlock circuits, and logic-level translation around higher-voltage signals. The four channels can be used independently, or several channels can implement window comparison, fault detection, and redundant monitoring functions. A common ground and supply arrangement simplifies multi-channel designs while requiring attention to common-mode limits, output pull-up placement, and input protection. The principal design consideration is ensuring that input and output conditions remain within the comparator's absolute maximum and common-mode limits. Input protection may be required when external wiring exposes the device to transients or voltages outside the normal operating range. The open-collector outputs also need suitable pull-up resistors, with resistance selected from the required sink-current, rise-time, and bus-loading constraints rather than from resistance alone. This page combines manufacturer specifications, verified distributor information, pin-level implementation guidance, and same-footprint replacement analysis. It also identifies the practical trade-offs among closely related LM2901-family ordering options so that engineers can distinguish electrical compatibility, package identity, and qualification differences before committing a design to production.

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.

Typical applications include industrial measurement, transducer interfaces, audio and control circuits, low-frequency active filters, sensor amplifiers, and general-purpose analog signal conditioning. Because it is a general-purpose amplifier, the LM2902D is most appropriate when system cost, supply tolerance, and availability matter more than very low offset, rail-to-rail operation, or high-frequency precision. The primary design consideration is supply and signal-range verification. Confirm that every input and output remains within the device's specified operating limits under load, temperature, and supply variation. Decoupling capacitors should be placed close to the supply pins, and each amplifier channel requires appropriate feedback and biasing.

An operational amplifier, commonly shortened to op amp, is an analog integrated circuit that amplifies the difference between two input voltages. A quad operational amplifier integrates four amplifiers into one package. Within the device hierarchy, LM2902DG belongs to the operational-amplifier, analog-amplifier, and integrated-circuit categories. 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. Because the four channels share one package, designers must consider common supply and ground connections, output-current behavior, stability with capacitive loads, and power dissipation when all channels operate simultaneously. 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. It is intended to help engineers determine package compatibility, verify key operating limits, and select a replacement without overlooking changes in amplifier performance or environmental requirements.

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.

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 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.

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.

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.
