Section 28 A/D Converter
28.7
When using the A/D converter, note the points listed in section 28.7.1 below.
28.7.1
• Analog Input Voltage Range: During A/D conversion, the voltages input to the analog input
• Set the AV
28.7.2
To prevent damage from voltage surges at the analog input pins (AN2 to AN7), connect an input
protection circuit like the one shown in figure 28.9. The circuit shown also includes an RC filter to
suppress noise. This circuit is shown as an example; The circuit constants should be selected
according to actual application conditions. Table 28.5 lists the analog input pin specifications and
figure 28.10 shows an equivalent circuit diagram of the analog input ports.
