30mA, 200V Power Amplifier with Low Bias Current

  • Wide Voltage supply operation – ±32V to ±150V (PA82J)
  • Protected output – thermal shutoff
  • Low bias current, low noise – FET input

 PA81J / PA82J Data Sheet

The PA81J and PA82J are high voltage power operational amplifiers that provide a wide range of supply capability. The PA81J is a 200V supply, 30mA output device, and the PA82J is a 300V supply, 15mA version. High accuracy is achieved with a cascode input circuit configuration.

Target applications for these devices include high impedance buffers, electrostatic transducers and deflection, and programmable power supplies. These hybrid designed products are 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.
