LM2902BYQ5T

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902BYQ5T is an automotive-grade, low-power quad operational amplifier manufactured by STMicroelectronics. It features a gain-bandwidth product of 1.2 MHz and a slew rate of 750 mV/us. The device operates within a supply voltage range of 3 V to 36 V, with a typical quiescent current of 350 uA per channel. Key electrical parameters include an input offset voltage of 4 mV, input bias current of 150 nA, and output short-circuit protection supporting up to 32 mA per channel. It utilizes a QFN-16 package and meets AEC-Q100 qualification standards for automotive applications.

• Internal frequency compensation for stability

Instrumentation, Op Amps, Buffer Amps Applications

• Automotive sensor signal conditioning
• Industrial control system amplification
• Battery management system monitoring

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'Q5T' against the manufacturer's official datasheet to confirm the exact reel quantity and tape-and-reel specifications. Ensure the component matches the required AEC-Q100 grade for your target application environment. Cross-reference the QFN-16 package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high common-mode rejection and wide supply voltage tolerance are required in space-constrained designs. The rail-to-rail input feature simplifies interface design for single-supply systems. Consider the 36 V maximum rating for robustness against transient voltage spikes common in automotive environments compared to standard industrial op-amps.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LM2902B family of low-power bipolar operational amplifiers. Unlike the standard LM2902 which typically supports up to 30 V, the BY variant extends the maximum supply voltage to 36 V. The Q5T designation indicates the specific automotive qualification and packaging format, distinguishing it from commercial grade or through-hole variants like the PT or D packages.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes within the same automotive grade may include other STMicroelectronics quad op-amps with similar bandwidth and voltage ratings. Verify that any replacement maintains the 36 V maximum supply rating and AEC-Q100 certification if used in automotive contexts.
