* - 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 nonlinearity (INL) errors.
  2. The ADC conversion result never decreases with an increase in the input and has no missing codes.
