The OPA188AIDBVT is a precision low noise rail-to-rail output zero-drift Operational Amplifier uses TI proprietary auto-zeroing techniques to provide low offset voltage (25μV maximum) and near zero-drift over time and temperature. This miniature, high-precision, low-quiescent current amplifier offers high input impedance and rail-to-rail output swing within 15mV of the rails. The input common-mode range includes the negative rail.
