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.
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.
This is the impedance seen by the VREF pads when the external reference pads are selected.
