PA40

HIGH VOLTAGE POWER OPERATIONAL AMPLIFIER PA40 M I C R O T E C H N O L O G Y 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.
