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 and 5VSB voltage can directly connected to these analog inputs.
The +12V,-12V and -5V voltage inputs should be reduced a factor with external resistors so as to
obtain the input range. As Figure 9.2 shows.
