LPV811DBVT

Instrumentation, Op Amps, Buffer Amps Overview

The LPV811DBVT is a single-channel precision operational amplifier from Texas Instruments, housed in a 5-pin SOT-23 package. It operates on a supply voltage range of 1.6 V to 5.5 V with a typical quiescent current of 425 nA per channel. Key electrical parameters include a gain-bandwidth product of 8 kHz, an input offset voltage maximum of 300 µV, and an input bias current of 100 fA. The device features rail-to-rail output capability, a slew rate of 1.7 mV/µs, and an input voltage noise density of 420 nV/√Hz at 1 kHz. It supports operation across a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'DBVT' corresponds to the SOT-23-5 package and tape-and-reel delivery format. Confirm that the component meets AEC-Q100 qualification requirements if automotive application is intended. Ensure the operating environment stays within the specified -40°C to +125°C temperature range to maintain guaranteed electrical characteristics.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing systems requiring ultra-low power consumption alongside high DC precision. It is suitable for battery-operated devices where minimizing quiescent current is critical without sacrificing signal integrity. Consider its 8 kHz bandwidth limitation for slow-changing sensor signals rather than high-frequency processing tasks.
