(Continued)
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 is longer than the minimum value.
The relationship between the external impedance and minimum sampling time
If the sampling time cannot be sufficient, connect a capacitor of about 0.1
F to the analog input pin.
<About errors>
As
AVR AVss become smaller, values of relative errors grow larger.
