LPV321M5X/NOPB

Instrumentation, Op Amps, Buffer Amps Overview

The LPV321M5X/NOPB is a single-channel general-purpose operational amplifier manufactured by Texas Instruments, formerly National Semiconductor. It features rail-to-rail input and output capabilities with a gain-bandwidth product of 1 MHz and a slew rate of 0.6 V/µs. The device operates on a supply voltage range of 2.7 V to 5.5 V, drawing a typical quiescent current of 400 µA per channel. It offers an input offset voltage of 3 mV and an input bias current of 2 nA. The component is housed in a SOT-23 (DBV) five-pin package and supports operation from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor, when sourcing this component. Confirm the specific suffix NOPB indicates lead-free and RoHS compliance status according to current datasheets. Ensure the package type matches the required SOT-23 footprint for PCB layout compatibility. Cross-reference the part number with official TI documentation to confirm active production status and availability.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring single-supply operation with rail-to-rail performance. Consider its low quiescent current for power-sensitive designs. Compare its bandwidth and slew rate against higher-speed alternatives if signal fidelity at higher frequencies is critical. Evaluate the SOT-23 package constraints regarding thermal dissipation and pin pitch for assembly processes.
