PA89A [Apex Microtechnology]

The PA89 is an ultra high voltage, MOSFET operational amplifier designed for output currents up to 75 mA. Output voltages can swing over 1000V p-p. It features a safe operating area with no second breakdown limitations, high accuracy with cascode input circuit and 120dB open loop gain, wide supply range ±75V to ±600V, and excellent supply rejection. The MOSFET output stage is biased for class A/B linear operation with external compensation flexibility. It is hermetically sealed in a MO-127 package, tested to MIL-STD-883 method 1014, and uses a Beryllia substrate for reliability and performance.
