Section 22 A/D Converter
22.7.9
A protection circuit connected to prevent damage due to an abnormal voltage such as an excessive
surge at the analog input pins (AN0 to AN7) should be connected to AV
figure 22.14. Also, the bypass capacitors connected to AV
connected to the AN0 to AN7 pins must be connected to AV
AV
If a filter capacitor is connected, the input currents at the AN0 to AN7 pins are averaged, and so an
error may arise. Also, when A/D conversion is performed frequently, as in scan mode, if the
current charged and discharged by the capacitance of the sample-and-hold circuit in the A/D
converter exceeds the current input via the input impedance (R
input pin voltage. Careful consideration is therefore required when deciding the circuit constants.
