General Description

The OPA188 operational amplifier uses TI's proprietary auto-zeroing techniques to provide low offset voltage (25-μV maximum) and near zero-drift over time and temperature.

This miniature, highprecision, low-quiescent current amplifier offers high input impedance and rail-to-rail output swing within 15 mV of the rails.

The input common-mode range includes the negative rail.
