AT42QT1060-MMUR Description

The AT42QT1060-MMUR is a digital burst mode charge-transfer (QT™) capacitive sensor driver designed specifically for mobile phone applications. The AT42QT1060-MMUR can sense from two to six keys; up to four keys can be disabled by not installing their respective sense capacitors (Cs). It also has up to seven configurable input/output lines, with Pulse Width Modulation (PWM) for driving LEDs. This AT42QT1060-MMUR includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions, and the outputs are fully de-bounced. Only a few external parts are required for operation.
