Typical Application

The OPAx277 family offers outstanding dc precision and ac performance. These devices operate up to 36-V supply rails and offer ultralow offset voltage and offset voltage drift, as well as 1-MHz bandwidth and high capacitive load drive. These features make the OPAx277 a robust, high-performance operational amplifier for high-voltage industrial applications.
