PCF8883T/1

PCF8883T/1
Capacitive proximity switch with auto-calibration, large voltage operating range and very low power consumption, SOIC8, NXP, RoHS


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 IC or remotely using a coaxial cable.
