PCF8885

Capacitive 8-channel touch and proximity sensor with

auto-calibration and very low power consumption

Rev. 3 — 17 March 2014

Product data sheet

1. General description

The integrated circuit PCF8885 is a capacitive 8-channel touch and proximity sensor that

uses a patented (EDISEN) method to detect a change in capacitance on remote sensing

plates. Changes in the static capacitances (as opposed to dynamic capacitance changes)

are automatically compensated using continuous auto-calibration. Remote sensing plates

(for example, conductive foils) can be connected to the IC

using coaxial cable. The eight

input channels operate independently of each other. There is also a built-in option for a

matrix arrangement of the sensors: interrupt generation only when two channels are

activated simultaneously, suppression of additional channel outputs when two channels

are already active.
