PCF8883 Datasheet (NXP Semiconductors) - Capacitive touch/proximity switch

PCF8883, Capacitive touch/proximity switch

The integrated circuit PCF8883 is a capacitive proximity switch that uses a patented (EDISEN) digital method to detect a change in capacitance on a remote sensing plate.

Changes in the static capacitance (as opposed to dynamic capacitance changes) are automatically compensated using continuous auto-
