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