Description

The PA98 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)PA98A  has no second breakdown limitations and can be observed with all types of loads by choosing an appropriate current limiting resistor. High accuracy of PA98A is achieved with a cascode input circuit configuration. All internal biasing of PA98A is referenced to a bootstrapped zener-MOSFET current source.As a result, the PA98 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 PA98A, 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 Power SIP package of PA98A is electrically isolated.
