The PA92 is a high voltage, low quiescent current
MOSFET operational amplifier designed as a low cost
solution for driving continuous output currents up to 4A
and pulse currents up to 7A. The safe operating area
(SOA) has no second breakdown limitations and can
be observed for all type loads by choosing an appropri-
ate current limiting resistor. The MOSFET output stage
is biased AB for linear operation. External compensa-
tion 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 den-
sity circuit boards. The Power SIP package is electri-
cally isolated.
