During A/D conversion cycle. Note 1: When A/D is off, it will not consume any current other than minor leakage current. The power-down current specification includes any such leakage from the A/D module. 2: The A/D conversion result never decreases with an increase in the input voltage and has no missing codes. 3: VREFH current is from RA3/AN3/VREF+ pin or AVDD, whichever is selected as the VREFH source. VREFL current is from RA2/AN2/VREF- pin or AVSS, whichever is selected as the VREFL source. 125 126 Note: Refer to Figure 22-5 for load conditions. RB1/AN5/TX/ RB4/AN6/RX/ DT/KBI0 pin CK/INT1 pin |
