LMV931MF

Instrumentation, Op Amps, Buffer Amps Overview

The LMV931MF is a single-channel operational amplifier manufactured by National Semiconductor, now part of Texas Instruments. It operates on a supply voltage range from 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 1.4 MHz, a slew rate of 0.6 V/µs, and an input offset voltage maximum of 6 mV. The device draws a typical supply current of 270 µA per channel and provides an output short-circuit current capability of 100 mA. It is housed in a 5-pin SOT-23 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required tape-and-reel or cut-tape packaging format. Confirm RoHS compliance status through the official datasheet before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a low-voltage, single-supply op-amp with rail-to-rail I/O is required. Compare the 1.4 MHz bandwidth and 6 mV max offset against application requirements. Consider the SOT-23-5 package constraints for thermal management and PCB layout space.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LMV93x-N family of low-voltage operational amplifiers. The family includes dual (LMV932) and quad (LMV934) variants sharing similar electrical characteristics. The 'N' suffix typically denotes the lead-free/RoHS compliant version produced under the Texas Instruments portfolio following the acquisition of National Semiconductor.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same family include the LMV932MFX/NOPB (dual channel) and LMV934MFX/NOPB (quad channel). Other compatible single-channel alternatives may include the LMV321 series, though electrical specifications such as offset voltage and bandwidth should be verified against the original design requirements.
