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 V
REF
+ and V
REF
- 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.
