If the conditions below are not met, the reliability of the device may be adversely affected.
• Analog input voltage range
• Relationship between AVcc, AVss and Vcc, Vss
• AV
19.7.5
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 AN15), and analog power supply
(AVcc) by the analog ground (AVss). Also, the analog ground (AVss) should be connected at one
point to a stable ground (Vss) on the board.
The voltage applied to analog input pin ANn during A/D conversion should be in the range
AVss ≤ VAN ≤ AV
Set AVss = Vss for the relationship between AVcc, AVss and Vcc, Vss. If the A/D converter
is not used, the AVcc and AVss pins must not be left open.
