PA89, PA89A PA89 • PA89A PA89 • PA89A High Voltage Power Operational Amplifiers FEATURES • 1140V P-P SIGNAL OUTPUT • WIDE SUPPLY RANGE — ±75V to ±600V • PROGRAMMABLE CURRENT LIMIT • 75 mA CONTINUOUS OUTPUT CURRENT • HERMETIC SEALED PACKAGE • INPUT PROTECTION PATENTED APPLICATIONS HIGH VOLTAGE MO-127 • PIEZOELECTRIC POSITIONING PACKAGE STYLE DC • HIGH VOLTAGE INSTRUMENTATION TYPICAL APPLICATION • ELECTROSTATIC DEFLECTION Ultra-high voltage capability combined with the bridge am- • SEMICONDUCTOR TESTING plifier configuration makes it possible to develop +/–1000 volt peak swings across a piezo element. A high gain of –50 for DESCRIPTION A1 insures stability with the capacitive load, while “noise-gain” The PA89 is an ultra high voltage, MOSFET operational ampli- compensation Rn and Cn on A2 insure the stability of A2 by fier designed for output currents up to 75 mA. Output voltages operating in a noise gain of 50. can swing over 1000V p-p. The safe operating area (SOA) has 50R 50R no second breakdown limitations and can be observed with
