Pointing devices Remote controls QT1080 charge-transfer (’QT’) QTouch IC is a self-contained digital controller capable of detecting near-proximity or touch on up to eight electrodes. It allows electrodes to project independent sense fields through any dielectric such as glass or plastic. This capability coupled with its continuous self-calibration feature can lead to entirely new product concepts, adding high value to product designs. The devices are designed specifically for human interfaces, like control panels, appliances, gaming devices, lighting controls, or anywhere a mechanical switch or button may be ...
