19.9.2
To prevent damage from voltage surges at the analog input pins (AN0 to AN3), connect an input
protection circuit like the one shown in figure 19.11. 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 19.4 lists the analog input pin specifications and
figure 19.12 shows an equivalent circuit diagram of the analog input ports.
