The OPA593 is an 85 V wide bandwidth (18 MHz), precision op amp with high output current (200 mA)

The OPA593 is a high voltage (85 V), wide bandwidth (10 MHz), high output current (250 mA), unity gain stable ACPM-5007-TR1 operational amplifier.

The OPA593 uses laser trimming to improve offset voltage (10 μV) and offset voltage drift (0.4 μV/°C), eliminating the need for calibration. External resistors can be used to limit current (±10% accuracy), providing more accurate measurements. If an overcurrent or overtemperature condition occurs, the device indicates erroneous operation with status flags. An included disable function can be used to shut down the device, save power and place the output in a high impedance state.

The device is unity-gain stable and can be used as a high impedance buffer, while the wide bandwidth (10 MHz) and high slew (40 V/μs) enable high signal gain. High output current and capacitive drive allow the device to drive external FETs for higher system currents, such as in digital power supplies.
