LPV321M5

Instrumentation, Op Amps, Buffer Amps Overview

The LPV321M5 is a single-channel operational amplifier from Texas Instruments, housed in a surface-mount SOT-23 package with five pins. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. Key electrical specifications include a gain-bandwidth product of 1 MHz, a slew rate of 100 V/µs, and a maximum input offset voltage of 7 mV. The device draws a typical supply current of 60 nA per channel and provides a rail-to-rail output swing.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix (e.g., NOPB) against the manufacturer's datasheet to confirm pinout and electrical tolerances. Ensure the SOT-23-5 footprint matches the PCB design. Confirm RoHS compliance status if required by regulatory standards. Cross-reference the part number with official distributor catalogs to avoid counterfeit components.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel op amp with rail-to-rail output is required under a 5.5 V supply. It is appropriate for designs prioritizing minimal quiescent current alongside moderate bandwidth. Compare input offset voltage and bias current requirements against alternative LMV or OPA series devices if higher precision is needed.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LPV3xx family of general-purpose, low-voltage operational amplifiers. It shares architectural similarities with the LMV321 but offers improved speed characteristics. The M5 suffix indicates the specific SOT-23-5 packaging variant used for surface-mount assembly.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The LMV321M5/NOPB serves as a functional substitute within the same family, though it exhibits a lower slew rate of 1 V/µs compared to the LPV321M5's 100 V/µs. Designers must verify that the reduced speed of the replacement meets the application's transient response requirements.
