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 set for a gain of 38.5 boosting the 2.33V signa to 90V. The recommended compensation for gains above 3 is used. If capacitive loading is at least 330pF at all times, th recommended snubber network may be omitted. The 27 ohm resistor sets current limit to a nominal value of 111mA to insur peak currents out of at least 78mA
