The OPA598 is a high-voltage (85V), high-output-current (350mA), unity-gain-stable operational amplifier with a high bandwidth (10MHz).

The OPA598 power amplifier combines low offset voltage (50µV) and offset voltage drift (1µV/°C) with additional features, including a programmable current limit and overcurrent flags. The OPA598 features mux-friendly inputs that enable differential input voltage range to the supply rails and help improve settling performance in multichannel systems.

The programmable current limit can be set with an external resistor or voltage source to limit the output current and protect downstream devices. In case of an overcurrent or overtemperature condition, the device indicates erroneous operation through a status flag. An included disable feature is used to shut down the device, saving power and placing the output into a high-impedance state.

The device is unity-gain stable, enabling operation as a high-impedance buffer, while the wide bandwidth and high slew enable high signal gains. The high output current and capacitive drive allow the device to drive external field-effect transistors (FETs) used to provide higher system currents, such as in a digital power supply.

If higher dc precision is required then the OPA593 can be used as a direct replacement.
