• PROGRAMMABLE POWER SUPPLIES UP TO 440V
DESCRIPTION
The PA15 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 pro-
vides 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 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 PA15 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.
