Differential voltages are at the non–inverting input terminal with respect to the inverting input terminal. Note 2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15V, whchever is less. Note 3. Power dissipation must be considered to ensure maximun junction temperature (TJ) is not exceeded.
