LM2902M96 - Quad 1MHz Operational Amplifier | Harris Corporation
Teilenummer: LM2902M96 ✓ AktivLM2902M96 Übersicht
An operational amplifier is a voltage-amplified, high-gain analog building block used in sensing, buffering, amplification, filtering, and control circuits. The LM2902 belongs to the operational-amplifier hierarchy, which includes instrumentation amplifiers, buffer amplifiers, comparator-adjacent interface functions, and general-purpose signal-conditioning ICs. Its four integrated channels make it useful where multiple independent analog paths are required within the same subsystem.
The principal features of the LM2902M96 are its four-amplifier configuration, 1 MHz bandwidth indication, and 14-pin SOIC implementation. These characteristics make the device suitable for transducers, sensor conditioning, analog signal buffers, feedback networks, and general instrumentation. The single package also reduces the number of discrete components required when four amplifier channels are needed at the same time.
The M96 ordering code identifies the surface-mount 14-pin SOIC configuration. This package supports conventional PCB assembly and provides a practical option for industrial control and instrumentation designs requiring multiple analog channels. Because electrical ratings differ across the wider LM2902 family, designers should confirm supply voltage, input common-mode range, output swing, input bias current, output current, and temperature range against the applicable manufacturer datasheet before finalizing a design.
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 page organizes the LM2902M96's core technical identity, verified drop-in candidates, package considerations, commercial information, and application guidance. It also provides practical design notes intended to help engineers move from general amplifier selection to a board-level implementation while preserving the correct 14-pin footprint and checking device-specific electrical limits.

Typische Anwendungen
LM2902M96 ist geeignet für 6 Anwendungs: Industrial Sensor Signal Conditioning, Process Control Interface Module, Data Acquisition Front End, Test and Measurement Instrumentation, Communications Interface Conditioning, Power and Battery Monitoring.
Industrial Sensor Signal Conditioning
The LM2902M96 fits industrial sensor-conditioning boards that must amplify several low-frequency transducer channels. Its four operational amplifiers provide independent signal paths for position, pressure, temperature, or level sensors without requiring four separate packages, while the 1 MHz bandwidth is suitable for many slow control and monitoring signals. A practical implementation would allocate one channel to each conditioned sensor input and use the remaining channels for reference buffering or active filtering. Before release, verify the common-mode input range, offset, input bias current, output swing, and noise behavior against the actual sensor excitation and grounding scheme.
Empfohlen
Process Control Interface Module
The LM2902M96 is appropriate for a process-control interface that handles multiple analog command or measurement paths. Four channels can support sensor inputs, actuator feedback, and shared reference buffering within one 14-pin SOIC. The 1 MHz bandwidth provides ample margin for typical slow industrial control loops while keeping the device focused on low-frequency signal conditioning rather than high-speed data conversion. The design must account for common-mode voltage, output swing, capacitive loading, and stability at the selected gain. Power bypassing should be placed close to the supply pins, and protection structures should be selected to avoid unintended input clamping or excessive input current.
Empfohlen
Data Acquisition Front End
The LM2902M96 can form the analog front end of a multi-channel data-acquisition module when each sensor requires independent buffering or amplification. Its four channels and 1 MHz bandwidth allow several low-bandwidth inputs to share one package while preserving the same basic amplifier topology across the board. For multiplexed acquisition systems, the switching network and amplifier must be analyzed together to prevent settling errors and overload. Verify input bias current for high-impedance sensors, output settling behavior, common-mode limits, and noise performance. Stable feedback-network layout and short, guarded routing are especially important when small sensor signals are amplified near the practical noise floor.
Empfohlen
Test and Measurement Instrumentation
The LM2902M96 is suitable for low-frequency instrumentation requiring four reusable analog channels, such as buffer amplifiers, gain stages, difference amplifiers, and active filters. A 1 MHz characteristic supports general-purpose bench and embedded measurement functions without implying high-speed waveform performance. In a precision instrument, offset, bias current, output swing, and noise can set the measurement floor, so each must be checked against the selected gain and impedance. Use short feedback paths, decouple the supply near the device, and avoid driving excessively capacitive loads. The 14-pin SOIC also simplifies fanout when analog inputs and returns must be routed systematically.
Empfohlen
Communications Interface Conditioning
The LM2902M96 can condition slow analog portions of a communications interface, including receive-path buffers, threshold amplifiers, and gain stages around slower interface signals. Its four channels allow several related functions to be consolidated, and its 1 MHz bandwidth is more relevant to low-speed analog control than to high-rate data lines. Designers should avoid interpreting the bandwidth figure as a guarantee of high-speed digital or RF performance. Check the input common-mode range and output drive against the downstream circuit, maintain short feedback loops, and use local supply bypassing to limit coupling between channels. Ground-return planning is essential when the amplifier operates near noisy communication equipment.
Empfohlen
Power and Battery Monitoring
The LM2902M96 can support low-frequency monitoring functions in a power-management subsystem, such as buffered voltage measurements, current-sense amplification, threshold detection, and reference conditioning. Four channels make it possible to monitor several rails or sensor outputs without using separate amplifier packages. The 1 MHz bandwidth is suitable for many power-system monitoring waveforms, although transient bandwidth and output recovery require separate examination. The amplifier's input common-mode range must include the monitored voltages, and output swing must remain valid at the logic threshold. In battery-powered equipment, account for the device's supply current as well as its signal-path accuracy and verify its temperature rating for the intended operating environment.

Designhinweise
Do not treat every LM2902 order code as footprint-compatible with LM2902M96. The replacement candidates use a 14-pin SOIC or SOP configuration, but a double-row package must match the PCB land pattern and pin numbering exactly. Confirm the physical dimensions, pin-1 orientation, exposed thermal features, and terminal assignments from the manufacturer package drawing. Also compare the complete operating envelope, including supply voltage, common-mode range, output swing, and temperature grade.
Place the supply bypass capacitor and amplifier output components close to their associated pins and maintain short feedback loops. Because the LM2902M96 contains four channels, keep sensitive channel routing away from high-current outputs and switching nodes. Use a continuous ground reference beneath the device where practical, minimize loop area in feedback networks, and isolate analog and digital return currents to reduce channel-to-channel coupling.
The 1 MHz bandwidth indication makes this device primarily suitable for low-frequency amplification and signal conditioning. Verify the required closed-loop gain, noise gain, output capacitive load, and settling behavior for each channel. Add isolation resistors near capacitive loads when required by the stability analysis, and avoid assuming that equal gain stages will settle identically when driven by different source impedances or loads.
Check supply headroom against the amplifier's permitted operating range and the voltage present at the package pins during transients. Decouple each supply connection locally and provide adequate return-current paths. If the circuit handles battery voltage or industrial signals, include protection that does not clamp normal input common-mode operation or inject excessive leakage into a high-impedance sensor source.
