1. I: input pin, OD: open drain, PP: output push-pull pin, S: supply pin and SNS: capacitive sensing pin.
2. Use COG or NPO capacitor type.
3. If the active shield is unused, please connect this pin to V
4. Requires a low ESR, 1µF capacitor to ground. This output must not be used to power other devices.
5. Depending on the value of bits [1:0] of OPT0.
