PCA8886 Dual channel capacitive proximity switch

The PCA8886 is a low power dual channel capacitive proximity switch that uses a patented (EDISEN) digital method to detect a change in capacitance on remote sensing plates. Changes in the static capacitance (as opposed to dynamic capacitance changes) are automatically compensated using continuous au.

PCA8886 Features
