15.8.4
If the conditions below are not met, the reliability of the device may be adversely affected.
• Analog input voltage range
• Vref input range
15.8.5
Careful consideration is required in board design for noise countermeasures and in order to prevent
damage due to abnormal voltage, such as an excessive surge at the analog input pins (AN0 to AN3
or AN14 to AN15) and analog reference voltage pin (Vref).

Item
Analog input capacitance
Permissible signal source impedance
The voltage applied to analog input pin ANn during A/D conversion should be in the range
VSS ≤ ANn ≤ Vref.
The analog reference voltage input at the Vref pin set is the range Vref ≤ Vcc.
