DESCRIPTION

The PA93 is a high voltage, low quiescent current MOSFET operational amplifer designed as a low cost solution for driving continuous output currents up to 8A and pulse currents up to 14A. The safe operating area (SOA) has no second breakdown limitations and can be observed for all type loads 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 Precision Power’s Power SIP package uses a minimum of board space allowing for high density circuit boards. The Power SIP package is electrically isolated.
