The PA40 is set for a gain of 38.5 boosting the 2.33V signal to 90V. The recommended compensation for gains above 30 is used. If capacitive loading is at least 330pF at all times, the recommended snubber network may be omitted.

DESCRIPTION
The PA40 is a high voltage monolithic MOSFET operational amplifier achieving performance features previously found only in hybrid designs while increasing reliability. Inputs are protected from excessive common mode and differential mode voltages. The safe operating area (SOA) has no second breakdown limitations. External compensation provides the user flexibility in choosing optimum gain and bandwidth for the application. The PA40 is packaged in Apex's 7 LEAD TO220 package. The metal back of the package is tied to Vs. The 15 mil minimum spacing of the TO220 package is adequate to stand-off the 350V rating of the PA40. The user must insure that a minimum of 11 mils spacing is maintained between pins for the circuit board artwork. If spacing is less than 11 mils, the voltage must be derated.

Unless otherwise noted TC = 25°C, CC = 18pF, RC = 2.2K. DC input specifications are ± value given. Power supply voltage is typical rating. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to achieve high MTTF. Derate maximum supply voltage .5 V/°C below case temperature of 25°C. No derating is needed above TC = 25°C. Sample tested by wafer to 95%. Guaranteed but not tested.
CAUTION
The PA40 is constructed from MOSFET transistors. ESD handling procedures must be observed.
