NOTES: 1. All voltage values, except differential voltages, are with respect to the network ground terminal.

2. Differential voltages are at the noninverting input terminal with respect to the inverting input terminal.

3. Short circuits from the output to VCC can cause excessive heating and eventual destruction.
