All voltage values, except differential voltage, are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of the input and the output voltages must never exceed the magnitude of the possitive supply voltage. 4. Guaranteed by design. 5. Short circuit from outputs to Vcc+ can cause excessive heating and eventual destruction. 6.
