Description

The PA83 is a high voltage operational amplifier designed for output voltage swings up to ±145V with a dual (±) supply or 290V with a single supply.PA83 input stage is protected against transient and steady state overvoltages up to and including the supply rails. High accuracy is achieved with a cascode input circuit configuration. All internal biasing of PA83 is referenced to a zener diode fed by a FET constant current source. As a result, the PA83 features an unprecedented supply range and excellent supply rejection. The output stage is biased in the class A/B mode for linear operation. Internal phase compensation of PA83 assures stability at all gain settings without need for external components. Fixed current limits protect these amplifiers against shorts to common at supply voltages up to 120V. For operation into inductive loads, two external flyback pulse protection diodes are recommended. However, a heatsink may be necessary to maintain the proper case temperature under normal operating conditions.

This hybrid circuit utilizes beryllia (BeO) substrates, thick (cermet) film resistors PA83, ceramic capacitors and silicon semiconductor chips to maximize reliability, minimize size and give top performance. Ultrasonically bonded aluminum wires provide reliable interconnections at all operating temperatures. The 8-pin TO-3 package of PA83 is hermetically sealed and electrically isolated. The use of compressible thermal isolation washers and/or improper mounting torque voids product warranty. Please see Application Note 1 "General Operating Considerations".

The PA83A is the A grade version, the PA83M/883 is the certified military grade version.
