DESCRIPTION

ThePA15FLisahighvoltage,lowquiescentcurrentMOSFET

operationalampliﬁerdesignedasalowcostsolutionfordriving

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

alltypeloadsbychoosinganappropriatecurrentlimitingresistor.

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.

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.
