Capacitive 8-channel touch and proximity sensor with auto-calibration and very low power consumption Rev. 4 - 13 March 2014 Product data sheet 1. General description The integrated circuit PCA8885 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 pensated using continuous auto-calibration. Remote sensing plates (for example, conductive foils) can be connected to the IC1 using coaxial cable. The eight input channels operate independently of each other. There is also a built-in...
