6.3 Analog Inputs
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 V-core voltage, +3.3V, battery(pin 74) 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 6.2 shows.
