OPA378AIDBVT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA378AIDBVT is a single-channel precision operational amplifier manufactured by Texas Instruments. It features rail-to-rail input and output capabilities, making it suitable for low-voltage applications. Key electrical parameters include a gain-bandwidth product of 900 kHz and a slew rate of 400 mV/us. The device operates with an input offset voltage of 20 uV and an input bias current of 150 pA. It supports a supply voltage range from 2.2 V to 5.5 V and consumes 125 uA of operating current per channel. The output can source up to 30 mA, and the common-mode rejection ratio is 112 dB.
