5.3
The maximum input voltage of the analog pin is 4.096V because the 8-bit ADC has a 16mv LSB.
Really, the application of the PC monitoring would most often be connected to power suppliers. The
CPU Vcore voltage, +3.3V, battery(pin 74), AVCC(pin 114) and 5VSB voltage can directly connected
to these analog inputs. The +12V voltage inputs should be reduced a factor with external resistors so
as to obtain the input range. As Figure 3.2 shows.
