AT42QT2160-MMU

The AT42QT2160-MMU is a QMatrix Touch Sensor IC designed for use with up to 16 keys and a slider (constructed from 2 keys up to 8 keys). The device is a digital burst mode charge-transfer (QT™) sensor 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 I?C-compatible interface to allow key data to be extracted and to permit individual key parameter setup. The command structure is designed to minimize the amount of data traffic while maximizing the amount of information conveyed.
