10% and a 16 MHz machine clock
*2: For V

10% and an 8 MHz machine clock
*3: The current when the A/D converter is not operating or the CPU is in stop mode (for V
CC
= AV
CC
= AVRH = +5.0 V).
Notes: The error increases proportionally as |AVRH – AVRL| decreases.
The output impedance of the external circuits connected to the analog inputs should be in the following
range.
Output impedance of external circuit < approx. 10 k
If the output impedance of the external circuit is too high, the sampling time for the analog voltage may
be too short. (Sampling time = 3.8
μ
s (corresponds to 16 MHz internal operation if the multiplier is 4.))
Note: The above values are for reference only.
