SBOS925A December 2020 – January 2021 OPA391
The OPA391 features advanced output drive circuitry that can maintain stability even with capacitive loads as high as 1 nF. Many low-quiescent-current amplifiers exhibit poor stability when connected to a capacitive load as a result of the low levels of current used to bias the output stage. The OPA391 is designed with an output stage that adapts to high capacitive loads without sacrificing additional current consumption. This feature gives a highly stable device across all temperature and supply conditions, enabling robust system performance.
