PRELIMINARY
To satisfy the A/D conversion precision standard, consider the relationship between the external impedance and
minimum sampling time and either adjust the resistor value and operating frequency or decrease the external
impedance so that the sampling time (Tsamp) is longer than the minimum value. Usually, this value is set to 7
τ,
where
τ = RC. If you include the external input resistance (Rext) connected to the analog input, the sampling time
is expressed:
Tsamp [min] = 7.(Rext + R).C
If the sampling time cannot be sufcient, connect a capacitor of about 0.1 mF to the analog input pin.
About the error
The accuracy gets worse as |AVRH - AVRL| becomes smaller.

Reference values:
R = 2.6 k
