(3) Notes on Using A/D Converter
Input impedance of the analog input pins
The A/D converter used for the MB89930A series contains a sample hold circuit as illustrated below to fetch
analog input voltage into the sample hold capacitor for 16 instruction cycles after activating A/D conversion.
For this reason, if the output impedance of the external circuit for the analog input is high, analog input voltage
might not stabilize within the analog input sampling period. Therefore, it is recommended to keep the output
impedance of the external circuit low (below 4 k
) .
Note that if the impedance cannot be kept low, it is recommended to connect an external capacitor of about
0.1
μ
F for the analog input pin.
