(1) The analog input voltage range must be within the selected reference voltage range V_R+ to V_R– for valid conversion results.
(2) The internal reference supply current is not included in current consumption parameter I_{(ADC12_B)}.
(3) Approximately 60% (typical) of the total current into the AVCC and DVCC terminals is from AVCC.
