 PA84 Data Sheet

The PA84 is a 300V power operational amplifier designed for output voltage swings up to ±145V with dual supplies, or 290V single supply. Two additional versions are available. The PA84S is a fast settling version that can absorb differential input over voltages up to 100V. The base model PA84 and A grade version PA84A can handle differential input over voltages of up to 600V. Target applications include high voltage instrumentation, electrostatic transducers and deflection, and programmable power supplies.

The PA84 is a hybrid product design housed in an electrically isolated, hermetically sealed, 8-pin TO-3 metal package. For continuous operation under load, a heatsink of proper rating is recommended.
