Figure 6-100. Analog to Digital Converter Block Schematic Operation
The ADC converts an analog input voltage to a 10-bit digital value through successive approx-
imation. The minimum value represents GND and the maximum value represents the voltage
on the AREF pin minus 1LSB. Optionally, AV
connected to the AREF pin by writing to the REFSn bits in the ADMUX Register. The internal
voltage reference may thus be decoupled by an external capacitor at the AREF pin to improve
noise immunity.
The analog input channel is selected by writing to the MUX bits in ADMUX. Any of the ADC
input pins, as well as GND and a fixed bandgap voltage reference, can be selected as single
ended inputs to the ADC. The ADC is enabled by setting the ADC Enable bit, ADEN in ADC-
SRA. Voltage reference and input channel selections will not go into effect until ADEN is set.
The ADC does not consume power when ADEN is cleared, so it is recommended to switch off
the ADC before entering power saving sleep modes.
