Description

The PA88 is a high voltage, low quiescent current MOSFET operational amplifier designed for output currents up to 100mA. Output voltages can swing up to ±215V with a dual supply and up to +440 volts with a single supply. The safe operating area (SOA)PA88  has no second breakdown limitations of PA88 and can be observed with all types of loads by choosing an appropriate current limiting resistor. High accuracy of PA88 is achieved with a cascode input circuit configuration. All internal biasing of is referenced to a bootstrapped zener-MOSFET current source. As a result, the PA88 features an unprecedented supply range and excellent supply rejection. The MOSFET output stage is biased on for linear operation. External compensation of PA88 provides user flexibility.

This hybrid circuit utilizes beryllia (BeO)PA88 substrates, thick film resistors, ceramic capacitors and 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 is hermetically sealed and electrically isolated. The use of compressible thermal isolation washers and/or improper mounting torque will void the product warranty. Please see "General Operating Considerations".
