DESCRIPTION
The PA93 is a high voltage, low quiescent current MOSFET
operational amplifier designed as a low cost solution for driving
continuous output currents up to 8A and pulse currents up to
14A. The safe operating area (SOA) has no second break-
down 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 com-
pensation 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.

TYPICAL APPLICATION
Piezo positioning may be applied to the focusing of seg-
mented mirror systems. The composite mirror may be com-
posed of hundreds of elements, each requiring focusing under
computer control. In such complex systems the PA93 reduces
the costs of power supplies and cooling with its advantages of
low cost and low quiescent power consumption while increas-
ing circuit density with the SIP package.
