±
10%, and the machine clock is 8 MHz
*3: Current when the A/D converter is not operating and the CPU is stopped (when V
CC

CC
= AVRH = +5.0 V)
Notes:
The smaller | AVRH – AVRL |, the greater the error would become relatively.
The output impedance of the external circuit for the analog input must satisfy the following conditions:
The output impedance of the external circuit should be less than approximately 7 k
.
When using an external capacitor, it is recommended to have several thousand times the capacitance of
the internal capacitor as a guid, if one takes into consideration the effect of the divided capacitance between
the external capacitor and the internal capacitor.
If the output impedance of the external circuit is too high, an analog voltage sampling time might be insufficient
(sampling time = 3.75
μ
s @ at a machine clock of 16 MHz).
