PA94
PA94
The PA94 is a high voltage, MOSFET operational am-
plifier designed as a low cost solution for driving contin-
uous output currents up to 100mA and pulse currents
up to 200mA into capacitive loads. The safe operating
area (SOA) has no second breakdown limitations and
can be observed for all load types by choosing an ap-
propriate current limiting resistor. The MOSFET output
stage is biased AB for linear operation. External com-
pensation 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 density circuit boards.. The Power SIP package is
electrically isolated. Isolating thermal washers (TW13)
prevent arcing from pins to heatsink.
