PA44 General Description

The PA44 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 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 PA44 is packaged in Apex's PSOP1 non-hermetic surface mountable dual in line package. The metal back of the package is tied to-Vs.

PA45 General Description

The PA45 is a high power monolithic MOSFET operational amplifier that achieves performance levels unavailable even in many hybrid amplifier designs. Inputs are protected from excessive common mode and differential mode voltages as well as static discharge. The safe operating area (SOA) has no second breakdown limitations 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.

This circuit utilizes a beryllia (BeO) substrate to minimize thermal resistance. Ultrasonically bonded aluminum wires provide reliable interconnections at all operating temperatures. The 8-pin TO-3 package is hermetically sealed and electrically isolated. The use of compressible isolation washers and/or improper mounting torque will void the product warranty.
