7.4 Analog Inputs

The maximum input voltage of the analog pin is 2.048V because the 8-bit ADC has the 8mV LSB.

Actually, the application of the voltage monitoring would most often be connected to power suppliers.

The input voltage lower than 2.048V could directly connect to the analog inputs. The inputs voltage

higher than 2.048V should be reduced by external resistors so as to meet the input range. This is

shown in Figure 3.
