Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation as UTD Semiconductor Co., Limited or UMW when sourcing this component. Confirm the specific ordering suffix 'DBVR' corresponds to the SOT-23-5 package and tape-and-reel packaging format. Ensure compatibility with the specified operating temperature range of -25°C to +85°C for your application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring low-voltage operation down to 2.1 V and minimal power draw. The rail-to-rail performance makes it suitable for single-supply systems where signal swing must approach the supply rails. Consider the 1 MHz bandwidth for general-purpose signal conditioning tasks.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMV321 series of low-power, rail-to-rail operational amplifiers manufactured by UMT/UTD Semiconductor. The series includes dual (LMV358) and quad (LMV324) variants sharing similar electrical characteristics. The LMV321IDBVR specifically denotes the single-channel version in a compact SOT-23-5 package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Cross-reference with other manufacturers offering LMV321-compatible parts such as Texas Instruments or STMicroelectronics. Verify pinout compatibility and ensure that alternative components meet the 2.1 V minimum supply voltage requirement and SOT-23-5 package dimensions.
