Product Summary
The PA94 is a high voltage, MOSFET operational amplifier designed as a low cost solution for driving continuous 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 appropriate current limiting resistor. The MOSFET output stage of PA94 is biased AB for linear operation. External compensation provides flexibility in choosing bandwidth and slew rate for the application. Cirrus’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. The applications of the PA94 include high voltage instrumentation, programmable power supplies up to ±430V, mass spectrometers, semiconductor measurement equipment.
