PA88A

PA88 PA88A High Voltage Power Operational Amplifiers RoHS COMPLIANT FEATURES High Voltage— 450V (±225V) Low Quiescent Current — 2mA Output Current— 100mA Programmable Current Limit Low Bias Current — FET Input APPLICATIONS Piezoelectric Positioning High Voltage Instrumentation Electrostatic Transducers Programmable Power Supplies up to 440V DESCRIPTION The PA88 is a high voltage, low quiescent current MOSFET operational amplifier designed for output cur‐ rents up to 100mA. Output voltages can swing up to ±215V with a dual supply and up to +440 volts with a sin‐ gle 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‐MOSFET current source. As a result, the PA88 features an unprecedent...
