Apex Microtechnology PA46
The PA46 is a high power monolithic MOSFET operational amplifier that achieves performance levels unavailable even in many hybrid amplifier designs. 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. The PA46 is constructed from MOSFET transistors.| Part No. | PA46 |

DESCRIPTION
Inputs are protected from excessive common mode and differential mode voltages as well as static discharge. External compensation provides the user flexibility in choosing optimum gain and bandwidth for the application. Class C operation with resulting low quiescent current is pin programmable. A shutdown input turns off the output stage. This circuit utilizes a beryllia oxide (BeO) substrate to minimize thermal resistance. The 10-pin power SIP package is electrically isolated.
