SBOS659B January 2022 – August 2022 OPA593
The OPA593 is a high-voltage (85 V), wide bandwidth (10 MHz), high-output-current (250 mA), unity-gain-stable operational amplifier.
The OPA593 uses a laser trimming technique to improve the offset voltage (10 µV) and offset voltage drift (0.4 µV/°C), thus avoiding the need for calibration. An external resistor can be used to limit the current (±5% accuracy), thus providing more precise measurements. In case of an overcurrent or overtemperature condition, the device indicates erroneous operation through a status flag. An included disable feature can be used to shutdown 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 (10 MHz) and high slew (40 V/µs) enable high signal gains. The high output current and capacitive drive allow the device to drive external FETs used to provide higher system currents, such as in a digital power supply.
