LMV931Q1MFX/NOPB

Instrumentation, Op Amps, Buffer Amps Overview

The LMV931Q1MFX/NOPB is a single-channel operational amplifier from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It operates on a supply voltage range of 1.8 V to 5.5 V and features rail-to-rail input and output capabilities. Key electrical parameters include a gain-bandwidth product of 1.5 MHz, a slew rate of 420 mV/us, and an input offset voltage of 4 mV. The device draws 116 uA of operating supply current and provides 100 mA of output current per channel. It is housed in an SC-70-5 (SOT-23-5) surface-mount package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'MFX' indicates tape-and-reel packaging when ordering. Confirm that the 'Q1' designation aligns with required automotive qualification standards for your application. Ensure the SC-70-5 footprint matches your PCB layout constraints. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when automotive qualification is mandatory alongside low-voltage operation. The rail-to-rail I/O makes it suitable for single-supply applications where signal swing must utilize the full supply range. Consider the 1.5 MHz bandwidth for moderate-speed signal processing tasks within automotive environments.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMV931 family of low-power, rail-to-rail operational amplifiers. The Q1 variant specifically targets automotive markets, distinguishing it from commercial versions through rigorous qualification testing. It shares core electrical characteristics with other LMV931 models but includes enhanced reliability assurances for vehicular use.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LMV931MF/NOPB serves as a non-automotive equivalent with identical electrical performance but lacks AEC-Q100 certification.
