PCA8886 Datasheet (NXP) - Dual channel capacitive proximity switch

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
