DESCRIPTION
The PA91 is a high voltage, low quiescent current MOSFET operational amplifier designed 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 flexibility 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.

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 increasing circuit density with the SIP package.

Unless otherwise noted: TC = 25°C, DC input specifications are ± value given. Power supply voltage is typical rating. RC = 100 CC = 68pF. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to achieve high MTTF. +VS and VS denote the positive and negative power supply rail respectively. Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz. Derate max supply rating .625 V/°C below 25°C case. No derating needed above 25°C case. The PA91 is constructed from MOSFET transistors. ESD handling procedures must be observed. The exposed substrate contains beryllia (BeO). Do not crush, machine, or subject to temperatures in excess of 850°C to avoid generating toxic fumes.
