PCF8883 Rev. 01 — 16 October 2009 www.DataSheet4U.com Capacitive proximity switch with auto-calibration, large voltage operating range and very low power consumption Product data sheet 1. General description 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-calibration. Remote sensing plates (e.g. conductive foil) can be connected directly to the IC1 or remotely using a coaxial cable. 2.
