Semiconductor Measurement Equipment DESCRIPTION
The PA94 is a high voltage, MOSFET operational amplifier designed as a low cost solution for driving con‐
tinuous output currents up to 100mA and pulse currents up to 200mA into capacitive loads. The safe operat‐
ing area (SOA) has no second breakdown limitations and can be observed for all load types by choosing an
appropriate current limiting resistor. The MOSFET output stage is biased AB for linear operation. External
compensation provides flexibility in choosing bandwidth and slew rate for the application. Apex Microtech‐
nology’s Power SIP uses a minimum of board space allowing for high density circuit boards. The Power SIP is
electrically isolated. Isolating thermal washers (TW13) prevent arcing from pins to heatsink. …
