PCF8883 Datasheet Capacitive Touch/proximity Switch

Manufacturer: NXP Semiconductors

PCF8883 Overview

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 pensated using continuous auto-calibration. Remote sensing plates (e.g. conductive foil) can be connected directly to the IC1 or remotely using a coaxial cable. 2.
