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 VCC+ and The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is Differential voltages are the non-inverting input terminal with respect to the inverting input Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all Rth are typical The output may be shorted to ground or to either supply.
