TUE (Total Unadjusted Error) includes Offset, Gain, and Linearity errors of the ADC, multiplexer, and on-chip input attenuators, including an external series input
protection resistor value between 0 kΩ and 1 kΩ.

m
is the number of channels configured as analog inputs, plus 2 for the internal V

n
is the number of channels configured as external temperature channels (D1 and D2).

Open-drain digital outputs may have an external pull-up resistor connected to a voltage lower or higher than V
CC
(up to 6.5 V absolute maximum).

All logic inputs except ADD are tolerant of 5 V logic levels, even if V
CC
is less than 5 V. ADD is a three-state input that may be connected to V
