LMV821IDBVR

Instrumentation, Op Amps, Buffer Amps Overview

The LMV821IDBVR is a single-channel, low-voltage operational amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 5.5 V and features rail-to-rail output swing. The device provides a typical gain bandwidth product of 5.5 MHz at 5 V and a slew rate of 1.9 V/μs. It is characterized for operation from -40°C to 125°C. Key electrical specifications include an input offset voltage of up to 3.5 mV, an input bias current of 100 nA, and a supply current of 0.3 mA typ at 5 V. The component is housed in a 5-pin SOT-23 (DBV) package.
