PA98

PA98 PA98A Power Operational Amplifiers RoHS COMPLIANT FEATURES High Voltage — 450V (±225V) High Slew Rate — 1000V/μs High Output Current — 200mA APPLICATIONS High Voltage Instrumentation Piezo Transducer Excitation Programmable Power Supplies Up To 430V Electrostatic Transducers & Deflection DESCRIPTION The PA98 is a 450V high-power operational amplifier. This high voltage amplifier utilizes a MOSFET output stage and has a power bandwidth of up to 500 kHz. When operating within a safe operating area, the PA98 has a maximum continuous current of 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) has no second breakdown limitations and can be observed with all types of loads by choosing an appropriate current limiting resistor. High accuracy is achieved with a cascode input circuit configuration. All internal biasing is referenced to a bootstrapped zener-MO...
