Analog Inputs
The maximum input voltage of the analog pin is 4.096V because the 8-bit ADC has a 16mv LSB. Actually,
the application of the PC monitoring would most often be connected to power supply. The CPU V-core
voltage,+3.3V and battery voltage can directly connect to these analog inputs. The –5V, –12V and +12V inputs
should be reduced a factor with external resistors to meet the input range. As Figure 7 shows.

The value of R1 and R2 can be selected to 28K Ohms and 10K Ohms, respectively, when the input voltage V1 is
12V. The node voltage of +12VIN should be subject to under 4.096V for the maximum input range of the 8-bit
ADC. The pin 13 and pin 29 are discretely connected to the power supply +5V and 5VSB . There are two functions
in these pins with 5V. The first function is to supply internal analog power in the W83791D and the second one is
that these voltages are all connected to internal serial resistors to monitor the +5V and 5VSB voltage.
