LM2902MX/ELLI957

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902MX/ELLI957 is a low-power quad operational amplifier manufactured by Texas Instruments. It features four independent amplifiers within a single package, designed for general-purpose analog signal processing. The device operates with a wide supply voltage range and offers rail-to-rail input capability, allowing it to function effectively in single-supply applications. Key electrical characteristics include a gain-bandwidth product of approximately 1 MHz and a slew rate of 0.5 V/us. The component is housed in surface-mount packages such as SOIC-14 or TSSOP-14, suitable for automated assembly processes.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix ELLI957 against official Texas Instruments documentation to confirm exact packaging, tape-and-reel specifications, and regional distribution status. Ensure the procurement source provides valid traceability and authenticity certificates. Cross-reference the part number with the latest datasheet revision to confirm pinout compatibility and electrical tolerances before finalizing orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a low-cost, low-power quad amplifier is required for single-supply applications. It serves as a direct replacement for legacy LM2902 variants where rail-to-rail input performance is necessary. Consider the surface-mount package type for PCB space constraints. Evaluate the 1 MHz bandwidth and output drive capabilities against specific circuit requirements to ensure adequate performance margins.

Instrumentation, Op Amps, Buffer Amps Part Context

The LM2902 series represents an enhanced version of the industry-standard LM324 operational amplifier family. It offers improved performance characteristics while maintaining pin compatibility with older designs. The MX suffix typically denotes a small outline integrated circuit package. This series is widely used in consumer electronics and industrial control systems due to its balance of cost, performance, and availability.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible substitutes include LM2902N, LM2902KNSRG4, and LM2902KVQDRQ1 from Texas Instruments. Verify package dimensions and thermal characteristics when transitioning between through-hole and surface-mount variants. Ensure that automotive-grade requirements are met if selecting AEC-Q100 qualified alternatives like the LM2902BQ series.
