Overview
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...
