*2: For 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 = 3.0 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.
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, the sampling time might be insufficient (sampling
time = 3.75
μ
s at a machine clock of 16 MHz).
