Hi all,

감사합니다.

We know ADC and what its resolution means, a higher ADC resolution means longer conversion time and higher precision which can measure smaller voltage signal.

CapSense is actually a CDC(Cap to Digital Converter), the scan resolution of a widget is similar to the convert resolution of a ADC, a higher scan resolution means longer scanning time, higher sensitivity and can detect smaller cap change.  We usually set this parameter based on the thickness of overlay, the larger thickness of overlay, the larger scan resolution setting.
