(2) Notes on Using the A/D Converter
External impedance of analog input and its sampling time
The A/D converter has a sample and hold circuit. If the external impedance is too high to keep sufficient
sampling time, the analog voltage charged to the capacitor of the internal sample and hold circuit is
insufficient, adversely affecting A/D conversion precision. Therefore, to satisfy the A/D conversion precision
standard, considering the relationship between the external impedance and minimum sampling time, either
adjust the register value and operating frequency or decrease the external impedance so that the sampling
time is longer than the minimum value. In addition, if sufficient sampling time cannot be secured, connect
a capacitor of about 0.1 F to the analog input pin.
A/D conversion error
As |VCC
VSS| decreases, the A/D conversion error increases proportionately.
