Operation
Figure 16-1. Analog to Digital Converter Block Schematic
The ADC converts an analog input voltage to a 10-bit digital value through successive approxi-
mation. The minimum value represents GND and the maximum value represents the reference
voltage.The voltage reference for the ADC may be selected by writing to the REFS1:0 bits in
ADMUX. The VCC supply, the AREF pin or an internal 1.1V voltage reference may be selected
as the ADC voltage reference.
The analog input channel and differential gain are selected by writing to the MUX5:0 bits in
ADMUX. Any of the eight ADC input pins ADC7:0 can be selected as single ended inputs to the
ADC. For differential measurements all analog inputs next to each other can be selected as a
input pair. Every input is also possible to measure with ADC3. These pairs of differential inputs
are measured by ADC trough the differential gain amplifier.
