Notes on Using A/D Converter
Select the output impedance value for the external circuit of analog input according to the following conditions :
Output impedance values of the external circuit of about 5 k
or lower are recommended.
If external capacitors are used, a capacitance of several thousand times the internal capacitor value is recom-
mended in order to minimize the effect of voltage distribution between the external and internal capacitor.
Note: If the output impedance of the external circuit is too high, the sampling time for analog voltages may not be
sufficient (sampling period
= 2.00 s @ machine clock of 16 MHz) . The output impedance of the external
circuit can be set to approx. 15k
or lower , when the sampling period is set to 4.00 s.
About Error
The smaller the absolute value of | AVRH
AVRL | is, the greater the relative error is.
