PA95 MOSFET Operational Amplifier


Apex MOSFET operational amplifiers drive continuous output currents up to 100 mA and pulse currents up to 200 mA

The PA95 is a high-voltage, MOSFET operational amplifier designed as a low-cost solution for driving continuous output currents up to 100 mA and pulse currents up to 200 mA into capacitive loads. The safe operating 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 Microtechnology's Power SIP package uses minimum board space allowing for high-density circuit boards. The Power SIP package is electrically isolated. Isolating thermal washers (TW13) are recommended to prevent arcing from pins to heatsink.
