OPA188AIDBVT +BOM

Rail-to-Rail Output

OPA188AIDBVT General Description

The OPA188AIDBVT is a high-performance operational amplifier that leverages TI's innovative auto-zeroing techniques to deliver exceptional precision and stability. With a maximum offset voltage of 25 µV and minimal drift over time and temperature, this amplifier is ideal for demanding applications that require high accuracy. Its compact size and low quiescent current make it suitable for portable and battery-powered devices
