The NCS2191x family of high precision Zero-Drift Op Amps feature low input offset voltage and low offset drift over time and temperature. These devices have low quiescent current and low noise performance with a rail−to−rail output swing within 10 mV of the rails. The NCS21911 operates over a wide supply range from 4 V to 36 V. All versions are specified for operation from −40°C to +125°C. Automotive qualified options are available under the NCV prefix.
