Seen from datasheet of MBR3, VDD_ripple max is 50mV. What effects it'll have on the chip or capsense if ripple peak-to-peak of VDD is 200mV?
Thanks and regards.

Hi GrWa_2302706,
There might be changes in the sensor raw counts value due to supply voltage noises and the sensors might false trigger. It is recommended to use a stable power supply to ensure proper CapSense operation.
