DESCRIPTION
The PA69 is a high voltage, high speed, low idle cur-
rent op-amp capable of delivering up to 100mA 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.
