    Use QTouch Library version 5.0.8 or later.

    OR

    Disable the PTC before entering sleep mode.

  2. 2.Reduced ADC accuracy for Vdd from 2.7V to 4.1V.
    Description:
    • DNL less than -1 (missing codes) can be observed for ADC codes 256, 512 and 768.
    • Increased gain error.
    Fix/Workaround:
    Use Vdd below 2.7V or above 4.1V if accurate ADC is needed.
