SBOS925A December 2020 – January 2021 OPA391
The OPA391 is a low-offset, low-power e-trim operational amplifier (op amp) that uses a proprietary offset trim technique. This op amp offers ultra-low input offset voltage, drift and input bias current while achieving an excellent bandwidth-to-quiescient-current ratio. The OPA391 operates from 1.7 V to 5.5 V, is unity-gain stable, and is designed for a wide range of general-purpose and precision applications.
The output features an advanced output stage that tolerates high capacitive loading for solid and stable performance. The OPA391 strengths make this device an excellent amplifier for high-impedance sensors, where input bias current, offset voltage, and power consumption are critical.
