Product Overview
The AT42QT1110-AU is a Standardized Capacitive Touch Controller with configurable 11-key QTouch™ buttons with guard channels for reliable capacitive UIs. It can be used in any application that requires buttons. Its keys can be constructed in different shapes and sizes. The device includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions. The outputs are fully debounced. Only a few external parts are required for operation.
- Keys measured sequentially for better performance or in parallel groups for faster operation
- Configurable "Detect" outputs indicating individual key touch (7-key mode)
- Patented spread-spectrum charge-transfer (direct mode) technology
- 7mm Center-to-center or more (panel thickness dependent) key spacing
