DESCRIPTION
The PA97 is a high voltage MOSFET operational amplifier designed as a low cost solution for driving continuous output currents up to 10mA and pulse currents to 15mA into capacitive loads. The safe operating area (SOA) has no second breakdown limitations. The MOSFET output stage is biased class C for low quiescent current operation. External compensation provides flexibility in choosing bandwidth and slew rate for the application. APEX's SIP05 package uses a minimum of board space allowing for high density circuit boards.

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 PA97 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.

NOTES: 1. 2. 3. 4. 5.
Unless otherwise noted: TC = 25°C, DC input specifications are ± value given. Power supply voltage is typical rating. CC = 10pF. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to achieve high MTTF. Although supply voltages can range up to ± 450V the input pins cannot swing over this range. The input pins must be at least 30V from either supply rail but not more than 500V from either supply rail. See text for a more complete description of the common mode voltage range. 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.
CAUTION
The PA97 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.
