CAP1133-1-AIA-TR

CAP1133-1-AIA-TR is a 3-channel capacitive touch sensor with 3 LED drivers. It incorporates Right Touch® technology, which is a multiple-channel capacitive touch sensor with multiple power LED drivers. It contains three (3) individual capacitive touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor input automatically recalibrates to compensate for gradual environmental changes. It also contains three (3) LED drivers that offer full-on / off, variable rate blinking, dimness controls, and breathing. Each of the LED drivers may be linked to one of the sensor inputs to be actuated when a touch is detected. As well, each LED driver may be individually controlled via a host controller. It includes multiple pattern touch recognition that allows the user to select a specific set of buttons to be touched simultaneously. It is used in applications such as desktop and notebook PCs, LCD monitors, consumer electronics, and appliances.
