DESCRIPTION
The PA92 is a high voltage, low quiescent current MOSFET
operational amplifier designed as a low cost solution for driving
continuous output currents up to 4A and pulse currents up to
7A. The safe operating area (SOA) has no second breakdown
limitations and can be observed for all type loads by choosing
an appropriate current limiting resistor. The MOSFET output
stage is biased AB for linear operation. External compensation
provides flexibility in choosing bandwidth and slew rate for the
application. APEX’s Power SIP package uses a minimum
of board space allowing for high density circuit boards. The
Power SIP package is electrically isolated.

LOW POWER, PIEZOELECTRIC POSITIONING
Piezo positioning may be applied to the focusing of segment-
ed mirror systems. The composite mirror may be composed of
hundreds of elements, each requiring focusing under computer
control. In such complex systems the PA92 reduces the costs
of power supplies and cooling with its advantages of low cost
and low quiescent power consumption while increasing circuit
density with the SIP package.
