Note 1: The A/D conversion result never decreases with an increase in the input voltage.
2: Measurements are taken with the external AVREF+ and AVREF- 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).
