DESCRIPTION
The PA340 is a high voltage monolithic MOSFET oper- ational amplifier achieving performance features previ- ously found only in hybrid designs while increasing re- liability. Inputs are protected from excessive common mode and differential mode voltages. The safe operat- ing area (SOA) has no second breakdown limitations. External compensation provides the user flexibility in choosing optimum gain and bandwidth for the applica- tion. The surface mount package of the PA340CC is an in - dustry standard non-hermetic plastic 7-pin DDPAK.

3.2 OTHER STABILITY CONCERNS
- Gain must be calculated as a non-inverting circuit (equal input and feedback resistors can provide a signal gain
of -1, but for calculating offset errors, noise, and stability, this is a gain of 2).
- Including a feedback capacitor changes the feedback factor or gain of the circuit. Consider R IN = 4.7k, Rf = 47k
