1.
All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the supply voltages where the zero reference
level is the midpoint between V CC + and V CC - .
2.
The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.
3.
Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
4.
The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating
is not exceeded
