DESCRIPTION

The PA79 is a high voltage, high speed, low idle cur-

rent op-amp capable of delivering up to 200mA peak

output current. Due to the dynamic biasing of the input

stage, it can achieve slew rates over 350V/µs, while

only consuming less than 1mA of idle current. External

phase compensation allows great flexibility for the user

to optimize bandwidth and stability.

The output stage is protected with user selected cur-

rent limit resistor. For the selection of this current limit-

ing resistor, pay close attention to the SOA curves for

each package type. Proper heatsinking is required for

maximum reliability.
