DESCRIPTION
The PA15FL is a high voltage, low quiescent current MOSFET
operational amplifier designed as a low cost solution for driving
continuous output currents up to 200mA and pulse currents up
to 350mA into capacitive loads. 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 input stage has integrated static and differential
mode protection. The MOSFET output stage is biased AB for
linear operation. External compensation provides flexibility
in choosing bandwidth and slew rate for the application. The
10-pin 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 PA15FL 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.
