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 PA141 is packaged in a hermetically sealed TO-3 and all circuitry is isolated from the case by an aluminum nitride (AlN) substrate. The PA142 is packaged in APEX’s hermet...
