Description

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. The safe operating area (SOA)PA89A  has no second breakdown limitations of PA89A and can be observed with all types of loads of PA89A by choosing an appropriate current limiting resistor. High accuracy of PA89A is achieved with a cascode input circuit configuration and 120dB open loop gain. All internal biasing of PA89A is referenced to a bootstrapped zener- MOSFET current source, giving the PA89 a wide supply range and excellent supply rejection. The MOSFET output stage is biased for class A/B linear operation. External compensation provides user flexibility. The PA89 is 100% gross leak tested to military standards for long term reliability.

This hybrid integrated circuit of PA89A utilizes a beryllia (BeO) substrate, thick film resistors, ceramic capacitors and semiconductor chips to maximize reliability, minimize size and give top pe formance. Ultrasonically bonded aluminum wires provide reliable interconnections at all operating temperatures. The MO-127 High Voltage, Power Dip™ package is hermetically sealed and electrically isolated.
