This A/D converter charges a sampling capacitor for sampling during sampling time.
Therefore, only a leakage current flow when sampling is not in progress, and a current that charges the capacitor
flows during sampling. Consequently, the input impedance fluctuates depending on whether sampling is in
progress, and on the other states.
To make sure that sampling is effective, however, it is recommended to keep the output impedance of the analog
input source to within 10 k , and to connect a capacitor of about 100 pF to the ANI0 to ANI10 pins (refer to
Figure 12-22).
A series resistor string of several tens of k is connected between the AV
Therefore, if the output impedance of the reference voltage source is high, this will result in a series connection to
