The OPA455 is an operational amplifier (op amp) with a high voltage of 155 V, and a high current drive of 45 mA. This device is unity-gain stable, and features a gain-bandwidth product of 6.5 MHz. The high-voltage OPA455 offers excellent accuracy and wide output swing, and has no phase inversion problems that are typically found in similar op amps. The device can be applied in many common op-amp configurations requiring a supply voltage range from ±6 V to ±75 V.

The OPA455 features an enable-disable function that provides the ability to turn off the output stage and reduce power consumption when not being used. The device also features a Status Flag pin that indicates an overtemperature or overcurrent fault conditions.
