The OPA593 is a precision, high-voltage, high-output-current op amp. The device is capable of operating with supplies as low as ±4 V (8 V) and as high as ±42.5 V (85 V). The current limit feature limits the output current, up to ±250 mA, to a specified accuracy. With a small size, high operating voltage range, output current, and high dc precision, the device is designed to operate as a high-gain stage, capable of driving heavy loads and condition large signals. The additional features of the OPA593, including the current limit, overcurrent and overtemperature flags, thermal protection, output disable, and mux-friendly inputs, help protect both the op amp and the system from potential damage due to various fault conditions.
