PA341CE Apex Microtechnology

PA341 RoHS High Voltage Power Operational Amplifier COMPLIANT FEATURES RoHS Compliant Monolithic MOS Technology Low Cost High Voltage Operation 350V Low Quiescent Current Typ. 2.2mA No Second Breakdown High Output Current 120mA PEAK Available in Die Form CPA341 APPLICATIONS Piezo Electric Positioning Electrostatic Transducer and Deflection Deformable Mirror Focusing Biochemistry Stimulators Computer to Vacuum Tube Interface DESCRIPTION The PA341 is a high voltage monolithic MOSFET operational amplifier which achieves performance fea tures 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 lim itation and can be observed with all type loads by choosing an appropriate current limiting resistor. External compensation provides the user flexibility in choosing optimum gain and bandwidth for the application. The PA341CE is packaged in a hermetically sealed 8 pin TO 3 package. The metal case of the PA341CE is isolated in excess of full supply voltage. The PA341DF is packaged in a 24 pin PSOP (JEDEC MO166) package. The metal heat slug of the PA341DF is isolated in excess of full supply voltage. The PA341DW is packaged in Apex Microtechnologys hermetic ceramic SIP. The alumina ceramic isolates the die in excess of full supply voltage. Figure 1: Equivalent Schematic +V S CC1 C 2 C I LIM +IN -IN OUT -V S Apex Microtechnology Inc.
