DESCRIPTION
The PA91 is a high voltage, low quiescent current MOSFET operational amplier designed as a low cost solution for driving continuous output currents up to 200mA and pulse currents up to 350mA. 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 exibility 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 12-pin PowerSIP package is electrically isolated.
LOW POWER, PIEZOELECTRIC POSITIONING Piezo positioning may be applied to the focusing of segmented mirror systems. The composite mirror may be composed of hundreds of elements, each requiring focusing under computer control. In such complex systems the PA91 reduces the costs of power supplies and cooling with its advantages of low cost and low quiescent power consumption while increasi……
