DESCRIPTION
The PA90 is a high voltage, low quiescent current MOSFET
operational ampli铿乪r designed as a low cost solution for driving
continuous output currents up to 200mA and pulse currents
up to 350mA. 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 com-
pensation provides 铿俥xibility in choosing bandwidth and slew
rate for the application. APEX鈥檚 Power SIP package uses a
minimum of board space allowing for high density circuit boards.
The 12-pin PowerSIP 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 PA90 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.
