Disable the PTC before entering sleep mode.
5. Reduced ADC accuracy for V
dd
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 V
dd
below 2.7V or above 4.1V if accurate ADC is needed.
38.3 Rev. C - D
1. If the Peripheral Touch Controller (PTC) is enabled in sleep mode, the PTC might stop working.
Description: If the Peripheral Touch Controller (PTC) is enabled in sleep mode, the PTC
might stop working.
Fix/Workaround:
Use QTouch Library version 5.0.8 or later.
OR
Disable the PTC before entering sleep mode.
2. Reduced ADC accuracy for V
dd
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 V
dd
below 2.7V or above 4.1V if accurate ADC is needed.
38.4 Rev. A - D
1. Reduced ADC accuracy for V
dd
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 V
dd
outside the range 2.7V to 4.1V if accurate ADC is needed.
