PA89 • PA89A High Voltage Power Operational Amplifiers RoHS COMPLIANT FEATURES • 1140V P-P Signal Output • Wide Supply Range — ±75V to ±600V • Programmable Current Limit • 75 mA Continuous Output Current • Hermetically Sealed Package • Input Protection APPLICATIONS • Piezoelectric Positioning • High Voltage Instrumentation • Electrostatic Deflection • Semiconductor Testing DESCRIPTION The PA89 is an ultra high voltage, MOSFET operational amplifier designed for output currents up to 75 mA. Output voltages can swing over 1000V p-p. 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 and 120dB open loop gain.
