Note 1: The A/D conversion result never decreases with an increase in the input voltage and has no missing codes.
2: Measurements are taken with external VREF+ and VREF- used as the A/D voltage reference.
3: Impedance during sampling is at 3.3V, 25°C. This parameter is for design guidance only and is not tested.
