LPV321M7/NOPB

Instrumentation, Op Amps, Buffer Amps Overview

The LPV321M7/NOPB is a single-channel operational amplifier manufactured by Texas Instruments, part of the LPV321 series. It operates on a supply voltage range of 2.7 V to 5 V with a typical quiescent current of 9 µA per channel. Key electrical parameters include a gain-bandwidth product of 152 kHz, a slew rate of 100 mV/µs, and an input offset voltage of 7 mV. The device features rail-to-rail input and output capabilities, providing a maximum output current of 60 mA. It exhibits a common-mode rejection ratio of 71 dB and an input voltage noise density of 146 nV/√Hz. The component is housed in a SC-70-5 surface-mount package and functions within a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation as Texas Instruments despite the National Semiconductor heritage, as TI acquired NS. Confirm the specific suffix /NOPB indicates lead-free and RoHS compliance. Ensure the SC-70-5 package type matches your PCB footprint requirements. Cross-reference the datasheet revision date to ensure parameter accuracy against your design specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single op-amp with rail-to-rail I/O is required under 5 V supplies. Consider its 152 kHz bandwidth for low-frequency signal processing tasks. Evaluate the 9 µA quiescent current against system power budgets. Compare the 7 mV input offset voltage against precision requirements for your specific application circuit.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LPV321 family of low-power, rail-to-rail operational amplifiers. It represents the transition from National Semiconductor to Texas Instruments following the acquisition. The M7 suffix typically denotes specific tape and reel packaging or regional variants within the standard LPV321 line.
