OPA4188 - Zero-Drift Operational Amplifiers

📥 Download Datasheet

General Description

The OPA4188 operational amplifier uses TI proprietary auto-zeroing techniques to provide low offset voltage (25 μV, maximum), and near zero-drift over time and temperature.

These miniature, highprecision, low quiescent current amplifiers offer high input impedance and rail-to-rail output swing within 15 mV of the rails, making them ideal for industrial applications.

The input common-mode range includes the negative rail.
