The PA85 is a high voltage, high power bandwidth MOSFET operational amplifier designed for output currents up to 200mA. 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) PA85 has no second breakdown limitations and can be observed with all types of loads by choosing an appropriate current limiting resistor. High accuracy of PA85 is achieved with a cascode input circuit configuration. All internal biasing of PA85 is referenced to a bootstrapped zener-MOSFET current source. As a result, the PA85 features an unprecedented supply range and excellent supply rejection. The MOSFET output stage is biased on for linear operation. External compensation provides user flexibility.
This hybrid circuit utilizes thick film (cermet) resistors PA85, ceramic capacitors and silicon semiconductor chips of PA85 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 PA85 is hermetically sealed and electrically isolated. The use of compressible isolation washers voids the warranty.
