DESCRIPTION
The PA90 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. The safe oper-
ating 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. Exter-
nal compensation provides flexibility in choosing band-
width and slew rate for the application. Apex Precision
Power’s Power SIP package uses a minimum of board
space allowing for high density circuit boards. The 12-
pin PowerSIP package is electrically isolated.
