21.7
When using the A/D converter, note the following points.
21.7.1
21.7.2
To prevent damage from voltage surges at the analog input pins (AN0 to AN7), connect an input
protection circuit like the one shown in figure 21.9. 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 21.5 lists the analog input pin specifications and
figure 21.10 shows an equivalent circuit diagram of the analog input ports.
