16.7.3
Adding capacitance results in coupling with GND, and therefore noise in GND may adversely
affect absolute precision. 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, so acting as antennas.
16.7.4
If conditions shown below are not met, the reliability of the device may be adversely affected.
• Analog input voltage range
• Relation between AVcc, AVss and Vcc, Vss
• Vref setting range
The reference voltage at the Vref pin should be set in the range Vref ≤ AVcc.
16.7.5
In board design, digital circuitry and analog circuitry should be as mutually isolated as possible,
and layout in 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.
Also, digital circuitry must be isolated from the analog input signals (AN0 to AN7, AN12, AN13),
analog reference power supply (Vref), and analog power supply (AVcc) by the analog ground
(AVss). Also, the analog ground (AVss) should be connected at one point to a stable digital
ground (Vss) on the board.
The voltage applied to analog input pin ANn during A/D conversion should be in the range
AVss ≤ AVn ≤ Vref.
As the relationship between AVcc, AVss and Vcc, Vss, set AVcc ≥ Vcc and AVss = Vss. If
the A/D converter is not used, the AVcc and AVss pins must not be left open.
