22.7.6
Adding capacitance results in coupling with GND, and therefore noise in GND may adversely
affect absolute accuracy. Be sure to make the connection to an electrically stable GND such as
AVss.
Care is also required to insure that filter circuits do not communicate with digital signals on the
mounting board, acting as antennas.
22.7.7
If the conditions shown below are not met, the reliability of the LSI may be adversely affected.
• Analog input voltage range
• Relation between AV
• Vref setting range
22.7.8
In board design, follow the notes below.
1. Digital circuitry and analog circuitry should be as mutually isolated as possible, and layout in
2. Lines should be connected with the analog reference power supply pin (AV
3. The analog ground pin (AV
The voltage applied to analog input pin ANn during A/D conversion should be in the range

As the relationship between AV
If the A/D converter is not used, set AV
The reference voltage at the Vref pin should be set in the range Vref ≤ AV
which digital circuit signal lines and analog circuit signal lines cross or are in close proximity
should be avoided as far as possible. Failure to do so may result in incorrect operation of the
analog circuitry due to inductance, adversely affecting A/D conversion values. Moreover,
digital circuitry must be isolated from the analog reference power supply pin (V
