Section 27
27.7.7
Connect a protective circuit between AVcc and AVss, as shown in figure 27.9, to prevent damage
of analog input pins (AN0 to AN3) due to abnormal voltage such as excessive serge. Connect a
bypass capacitor that is connected to AVcc and a capacitor for a filter that is connected to AN0 to
AN3 to AVss.
When a capacitor for a filter is connected, input currents of AN0 to AN3 are averaged, may
causing errors. If A/D conversion is frequently performed in scan mode, voltages of analog input
pins cause errors when a current that is charged/discharged for capacitance of a sample & hold
circuit in the A/D converter is higher than a current that is input through input impedance (Rin).
Therefore, determine a circuit constant carefully.
