Infinite Operating Free-Air Temperature Range Storage Temperature Range 0 to +70 -40 to +125 -55 to +125 -65 to +150 o C All voltage values, except differential voltage, are with respect to network ground terminal. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. The magnitude of the input and +the output voltages must never exceed the magnitude of the positive supply voltage. Short circuit from outputs to VCC can cause excessive heating and eventual destruction.
