MB90650A Series
5. A/D Converter Electrical Characteristics
*1: For a 16 MHz machine clock
*2: For an 8 MHz machine clock
*3: The current when the A/D converter is not operating or the CPU is in stop mode (for V
Notes: • The error increases proportionally as |AVRH – AVRL| decreases.

• The output impedance of the external circuits connected to the analog inputs should be in the following
• If the output impedance of the external circuit is too high, the sampling time might be insufficient (sampling
• V
range.
The output impedance of the external circuit should be less than approximately 7 k
When using an external capacitor, it is recommended to have several thousand times the capacitance of
the internal capacitor as a guid, if one takes into consideration the effect of the divided capacitance between
the external capacitor and the internal capacitor.
