* - These parameters are characterized but not tested.

† Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not tested.

Note:
  1. Total Absolute Error is the sum of the offset, gain and integral non-linearity (INL) errors.
  2. The ADC conversion result never decreases with an increase in the input and has no missing codes.
