Note 1:
The A/D conversion result never decreases with an increase in the input voltage.
2:
Measurements are taken with the external AV
REF
+ and AV
REF
- used as the A/D voltage reference.
3:
Overall accuracy can be improved if 4 or more consecutive measurements are averaged. For details, see
the “PIC24F Family Reference Manual”, “12-Bit, High-Speed Pipeline A/D Converter” (DS30686).
