OPA2188 Zero-Drift Operational Amplifiers

The OPA2188 operational amplifier uses TI 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.
