1. All voltages, except differential I/O bus voltage, are with respect to the network ground terminal.

2. When the input voltage at any pin exceeds the power supplies (that is VIN < AGND or VIN > AVCC or DVCC), the current

at that pin should be limited to 10 mA. The 20 mA maximum package input current rating limits the number of pins that can

safely exceed the power supplies with an input current of 10 mA to two.

3. Short-circuits can cause excessive heating. Destructive dissipation can result from short-circuits on the amplifiers.

Note:

Absolute maximum ratings are those values beyond which damage to the device may occur. Functional

operation under these conditions is not implied. All values are referred to GND.
