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

1. Specifications are for individual amplifiers in PA443DF, unless otherwise noted.
2. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dis‐
sipation to achieve high MTTF. For guidance, refer to heatsink data sheet.
CAUTION
The PA441 and PA443 are constructed from MOSFET transistors. ESD handling procedures
must be observed.
