Section 18 A/D Converter
18.7.5
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.
18.7.6
If the conditions shown below are not met, the reliability of the LSI may be adversely affected.
• Analog input voltage range
• Relation between AVss and Vss, and AVcc and Vcc
• Vref setting range
Page 1062 of 1448
The voltage applied to analog input pin ANn during A/D conversion should be in the range
AVss ≤ V
As the relationship between AVss and Vss, set AVss = Vss. If the A/D converter is not used,
set AVcc = Vcc and AVss = Vss.
The reference voltage at the Vref pin should be set in the range Vref ≤ AVcc.
