PA441DW Apex Microtechnology

PA441/PA443 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 APPLICATIONS Piezo Electric Positioning Electrostatic Transducer and Deflection Deformable Mirror Focusing Biochemistry Stimulators Computer to Vacuum Tube Interface DESCRIPTION The PA441 is a high voltage monolithic MOSFET operational amplifier with improved noise and band- width performance compared to similar previous products. Features previously found only in hybrid designs are offered in this monolithic package, with improved reliability. Inputs are protected from excessive common mode and differential mode voltages. The safe oper- ating area (SOA) has no second breakdown limitation 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 PA441DF is packaged in a 24-pin PSOP (JEDEC MO-166) package. The metal heat slug of the PA441DF is isolated in excess of full supply voltage. The PA441DW is packaged in Apex Microtechnology s hermetic ceramic PIP. The alumina ceramic isolates the die in excess of full supply voltage. The PA443DF has two PA441 dies packaged in a 24 pin PSOP (JEDEC MO-166)package. The heatslug of the PA443DF package is isolated in excess of full supply voltage Apex Microtechnology Inc.
