These digital charge-transfer (QT) QMatrix ICs QT60248 are designed to detect human touch on up to 16 or 24 keys when used with a scanned, passive X-Y matrix. They will project touch keys through almost any dielectric, e.g. glass, plastic, stone, ceramic, and even wood, up to thicknesses of 5 cm or more. The touch areas are defined as simple 2-part interdigitated electrodes of conductive material, like copper or screened silver or carbon deposited on the rear of a control panel. Key sizes, shapes and placement are almost entirely arbitrary; sizes and shapes of keys CAN be mixed within a single panel of keys and CAN vary by a factor of 20:1 in surface area. The sensitivity of each key CAN be set individually via simple functions over the serial port by a host Microcontroller Key setups are stored in an onboard EEPROM and do not need to be reloaded with each powerup.
