7. Notes on Using A/D Converter
Input impedance of the analog input pins
The output impedance of the external circuit for the analog input must satisfy the following conditions.
If the output impedance of the external circuit is too high, an analog voltage sampling time might be insufficient
(sampling time = 6
μs at 10 MHz oscillation.) Therefore, it is recommended to keep the output impedance of the
external circuit below 10 k
Ω.
Error
The smaller the | AVR–AVss |, the greater the error would become relatively.
