1. All voltage values,except differential voltage ,are with respect to zero reference level (ground) of the supply
voltages where the zero reference level is the midpoint between Vcc+ and Vcc-.
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 interminal.
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.
