PA83

IC, OP-AMP, 60kHz, 30V/µs, TO-3-8

DESCRIPTION

The 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 configuration. 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.
