(2) Notes on Using the A/D Converter
• External impedance of analog input and its sampling time
• A/D conversion error
DS07-12623-5E
• The A/D converter has a sample and hold circuit. If the external impedance is too high to keep sufficient
• Analog input equivalent circuit
• Relationship between external impedance and minimum sampling time
As |V
sampling time, the analog voltage charged to the internal sample and hold capacitor 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 µF
to the analog input pin.
