AT42QT1481 Capacitive Touch Controller

Microchip Technology AT42QT1481 Capacitive Touch Controller is a digital burst mode sensor, designed specifically for QMatrix layout touch controls. The Microchip QMatrix sensing algorithm (mutual capacitance) enables the designers to achieve more buttons than there are pins because of this matrix layout. The AT42QT1481 allows a wide range of key sizes and shapes to be mixed together in a single touch panel. The AT42QT1481 is designed for use with up to 48 keys. The device includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions and frequencies. Only a few external parts are required for operation.
