The Power Reduction ADC bit, PRADC (see
page
The ADC converts an analog input voltage to a 10-bit digital value through successive
approximation. The minimum value represents 0V (conversion result 0x000) and the
maximum value in single ended mode represents the reference voltage minus 1 LSB
(conversion result 0x3FF). The reference voltage can be measured at the AREF pin.
The internal, generated reference voltage can have the values 1.5V, 1.6V or AVDD
where the 1.6V has the highest absolute accuracy. The reference voltage is selected by
writing to the REFSn bits in the ADMUX Register. An external reference voltage can
also be selected. Such an external voltage must be supplied with a very low impedance

an external capacitor. Adding unnecessary external capacitance at the AREF pin will
