Notes: The relative error becomes larger as the reference voltage (AVR) becomes smaller.
Be sure to use the A/D converter only when output impedance of the external analog input circuit meets
the following conditions.
External circuit output impedance < approx. 7 k
If the output impedance of the external circuit is too high, there may not be enough time to sample the
analog voltage. (Sampling time = 3.75
μ
s @4 MHz (equivalent to internal 16 MHz when multiplying by 4))
For an external capacitor to be provided outside the chip, its capacity should desirably be thousands times
larger than of the capacity in the chip taking in consideration the influence of the capacity destribution of
the external and internal capacitors.
