HTTP://WWW.APEXMICROTECH.COM (800) 546-APEX (800) 546-2739
FEATURES
• MONOLITHIC MOS TECHNOLOGY
• LOW COST
• HIGH VOLTAGE OPERATION—250V
• LOW QUIESCENT CURRENT—2mA
• NO SECOND BREAKDOWN
• HIGH OUTPUT CURRENT—120 mA PEAK
APPLICATIONS
• TELEPHONE RING GENERATOR
• PIEZO ELECTRIC POSITIONING
• ELECTROSTATIC TRANSDUCER & DEFLECTION
• DEFORMABLE MIRROR FOCUSING
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 250V 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.

Telephone Ring Generator
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.
