QT60240-ATG

The QT60240-ATG is a digital burst mode charge-transfer 24 Key QMATRIX™ Touch Sensor IC designed specifically for matrix layout touch controls, it includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions. The device uses an I²C interface to allow key data to be extracted and to permit individual key parameter setup. It allows a wide range of key sizes and shapes to be mixed together in a single touch panel. The command structure is designed to minimize the amount of data traffic while maximizing the amount of information conveyed.

• Patented spread-spectrum charge-transfer technology (transverse mode)
• Individually settable via simple commands over serial interface key sensitivity
• Adjacent key suppression
• Auto drift compensation
• Noise filtering
