 PA61 Data Sheet


The PA61 is a 10A PEAK, 90V power operational amplifier featuring a simple Class C complementary common emitter output stage that is optimized for low frequency applications where crossover distortion is not critical. Target applications include valve and actuator controls, DC or AC power regulators and motor/synchro drivers.

The PA61A is the A grade version providing enhance performance in the areas of offset voltage, offset current and bias current. The PA61M/883 is the fully certified military grade version. The PA61 series 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.
