Analog Inputs

The maximum input voltage of the analog pin is

4.096V, the 8-bit ADC has a 16mv LSB. For

most PC applications, the analog inputs are

connected to the power suppliers. The CPU V-

core voltage,+3.3V and battery voltage can

directly connected to these analog inputs. The

5VSB and +12V inputs should be reduced using

external resistors to obtain the proper input

range. Refer to Figure 11.
