The OPA593 is a precision, high-voltage (85 V), wide bandwidth (10 MHz), power operational amplifier (op amp) with a high output current drive of ±250 mA. The device features a current limit that helps protect the system in the event of an output short to ground. Unlike other power op amps, the current limit is specified for specific current ranges from ±25 mA to ±250 mA. Additionally, the device has two flags that indicate an overcurrent fault condition (beyond the configured limit) and an overtemperature fault condition (when the output stage shuts down to protect the device from overheating). Lastly, the output can be disabled to save system power and reduce thermal dissipation.

The unity-gain stable OPA593 has no phase inversion, a common-mode voltage range that includes the negative rail, a wide output swing range, and high dc precision. All these features make the OPA593 an excellent choice as an output driver for a device under test (DUT) in automated test equipment (ATE) systems, or for signal processing in industrial systems using signals greater than 36 V.
