Overview

The OPA593 is a high-voltage (85 V), power operational amplifier (op amp) with a high output current drive of 250 mA. The device features a current limit with an accuracy of ≤ 5% when the output current is greater than 50 mA. The current limit helps protect the system in the event of an output short to ground. 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 prevent damage to the device). Lastly, the output can be disabled to save system power and minimize thermal dissipation.

The unity-gain stable OPA593 has no phase inversion, a common-mode voltage range that includes the negative rail, a rail-to-rail output, and high dc precision. This device also has a wide signal range, 10 MHz of gain bandwidth, and high output current. 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.
