PA83A

PA83 PA83A High Voltage Power Operational Amplifiers RoHS COMPLIANT FEATURES Low Bias Current, Low Noise — FET Input Fully Protected Input — Up to ±150V Wide Supply Range — ±15V to ±150V APPLICATIONS High Voltage Instrumentation Electrostatic Transducers & Deflection Programmable Power Supplies up to 290V Analog Simulators DESCRIPTION The PA83 is a high voltage operational amplifier designed for output voltage swings up to ±145V with a dual (±) supply or 290V with a single supply. Its input stage is protected against transient and steady state overvoltages up to and including the supply rails. High accuracy is achieved with a cascode input circuit con‐ figuration. All internal biasing is referenced to a zener diode fed by a FET constant current source. As a result, the PA83 features an unprecedented supply range and excellent supply rejection. The output stage is biased in the class A/B mode for linear operation. Internal phase compens...
