(5) Precautionary Information
Input Impedance of Analog Input Pins
The A/D converter of MB89530A has a sample & hold circuit as shown below, which uses a sample-and-hold
capacitor to obtain the voltage at the analog input pin for 8 instruction cycles following the start of A/D conversion.
For this reason if the external circuits providing the analog input signal have high output impedance, the analog
input voltage may not stabilize within the analog input sampling time. It is therefore recommended that the output
impedance of external circuits be reduced to 10 k
or less.
About error
The smaller the absolute value |AVR - AVss| is, the greater the relative error becomes.
Analog Input Equivalent Circuit
C
R
Comparator
If analog input impedance is
10 k
or more, the use of a
capacitor of approximately
0.1
F is recommended.
