13.6
The following points should be noted when using the A/D converter.
13.6.1
Analog Input Voltage Range: The voltage applied to analog input pins during A/D conversion
should be in the range AV
AV
and AV
13.6.2
To prevent damage from surges and other abnormal voltages at the analog input pins (AN0–AN6),
connect a protection circuit such as that shown in figure 13.8. This circuit also includes a CR filter
function that suppresses error due to noise. The circuit shown here is only a design example;
circuit constants must be decided on the basis of the actual operating conditions.
Figure 13.9 shows an equivalent circuit for the analog input pins, and table 13.5 summarizes the
analog input pin specifications.
