Notes:
The smaller the | AVR – AV

|, the greater the error would become relatively.
The output impedance of the external circuit for the analog input must satisfy the following conditions:
Output impedance of the external circuit < Approx. 10 k
If the output impedance of the external circuit is too high, an analog voltage sampling time might be
insufficient (sampling time = 22
μ
s at 8 MHz oscillation).
