† 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 includes integral, differential, offset and gain errors.
2: The ADC conversion result never decreases with an increase in the input voltage and has no missing codes.
3: ADC VREF is from external VREF, VDD pin or FVR, whichever is selected as reference input.
4: ADC Reference Voltage (Ref+) is the selected reference input, VREF+ pin, VDD pin or the FVR Buffer1. When the FVR is
selected as the reference input, the FVR Buffer1 output selection must be 2.048V or 4.096V (ADFVR<1:0> =
1x).
Note: Refer to Figure 30-5 for load conditions.
