Notes on A/D Converter Section
Use the device with external circuits of the following output impedance for analog inputs:
Recommended output impedance of external circuits are: Approx. 3.9 k
or lower (4.5 V
AVcc
5.5 V)
(sampling period=2.00
μ
s at 16-MHz machine clock), Approx. 11 k
or lower (4.0 V
AVcc < 4.5 V) (sampling
period=8.0
μ
s at 16-MHz machine clock).
If an external capacitor is used, in consideration of the effect by tap capacitance caused by external capacitors
and on-chip capacitors, capacitance of the external one is recommended to be several thousand times as high
as internal capacitor.
If output impedance of an external circuit is too high, a sampling period for an analog voltage may be insufficient.
About errors
As
AVR-AVss
become smaller, values of relative errors grow larger.
