Precision, Low-Noise, Rail-to-Rail Output, 36V Zero-Drift Operational Amplifier

OPA188AIDBVR General Description

The OPA188AIDBVR operational amplifier from TI is a high-precision component designed for applications requiring low offset voltage and minimal drift. With a maximum offset voltage of 25µV and near zero-drift performance over time and temperature, this amplifier is ideal for critical measurement and control systems. Additionally, the OPA188 offers high input impedance and rail-to-rail output swing, providing versatility in a variety of circuit configurations
