NOTES:
1.Differential voltages are at the noninverting input terminal with respect to the inverting
input terminal.
2.The magnitude of the input voltage must never exceed the magnitude of the supply
or 15 V, whichever is less.
3.Power dissipation must be considered to ensure maximum junction temperature (TJ)
is not exceeded (see Figure 1).
