QT60240-ISG

The QT60240-ISG is a digital Burst Mode Charge-Transfer (QT) Sensor designed specifically for matrix layout 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 centimetres of single-sided PCB area. CEM-1 and FR1 punched, single-sided materials can be used for the lowest possible 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 two-sided adhesive acrylic film. The device employs transverse charge-transfer ('QT') sensing, a technology that senses changes in electrical charge forced across two electrode elements by a pulse edge. The device allows a wide range of key sizes and shapes to be mixed together in a single touch panel.
