DESCRIPTION
The PA78 is a high voltage, high speed, low idle current op-amp capable of delivering up to 200m A 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 1m A of idle current. External phase pensation allows great flexibility for the user to optimize bandwidth and stability. The output stage is protected with user selected current limit resistor. For the...
