Note 1:

Does not include current consumption due to external loading on pins.

Sample mode current is specified during an A/D inactive cycle. Sample mode average current can be

calculated using the formula: Average Sample Mode Supply Current = (IDDRUN + (n – 1) * IDDINS)/n; where

“n” is the programmed sample rate.

A/D accuracy is maintained between 2.7 volts and 4.5 volts.
