Description

Overview
QMatrix devices are digital burst mode charge-transfer (QT) sensors designed specifically for matrix geometry touch controls; they include all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions. Only a few external parts are required for operation. The entire circuit can be built within a few square centimeters of single-sided PCB area. CEM-1 and FR1 punched, single-sided materials can be used for possible lowest cost. The PCB’s rear can be mounted flush on the back of a glass or plastic panel using a conventional adhesive, such as 3M VHB 2-sided adhesive acrylic film.
QMatrix parts employ transverse charge-transfer (QT) sensing, a technology that senses changes in electrical charge forced across an electrode by a pulse edge (Figure 1-1).
QmBtn software for the PC can be used to program the operation of the IC as well as read back key status and signal levels in real time.
The parts are electrically identical with the exception of the number of keys which may be sensed.
