Up To ±150V Fully Protected Input, Low Bias Current Power AmplifierThe PA83 is a high voltage operational ampliier 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 coniguration. 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 com-
pensation assures stability at all gain settings without need
for external components. Fixed current limits protect these
ampliiers against shorts to common at supply voltages up to
120V. For operation into inductive loads, two external lyback
pulse protection Diodes are recommended. However, a heatsink
may be necessary to maintain the proper case temperature
under normal operating conditions. By Cirrus Logic, Inc.
