Description
AI
The OPA593 is a high-voltage (85 V), high-precision, wide-bandwidth (10 MHz), high-output-current (250 mA), unity-gain-stable, power op amp.
The OPA593 uses a laser trimming technique to improve the offset voltage (20 µV, typical) and offset voltage drift (0.4 µV/°C, typical), and thus avoids the need for calibration. This device featuresmux-friendlyinputs that enable differential input voltage range to the supply rails and help improve settling performance in multichannel systems.
An external resistor can be used to limit the current with specified accuracy, and thus provide more precise measurements. In case of an overcurrent or overtemperature condition, the device indicates erroneous operation through a status flag. An included disable feature is 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. 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.
