AT42QT1110-AUR Capacitive Touch Sensors

AT42QT1110-AUR Capacitive Touch Sensors QTouch 11 Key Touch Sensor IC.

• Sensor Keys: Up to 11 QTouch® channels
• Data Acquisition:  Measurement of keys triggered either by a signal applied to the SYNC pin or at
• regular intervals timed by the AT42QT1110 internal clock
•  Keys measured sequentially for better performance, or in parallel groups for faster operation
•  Raw data for key touches can be read as a report over the SPI interface
•  Discrete Outputs:  Configurable “Detect” outputs indicating individual key touch (7-key mode)
•  Device Setup:  Device configuration can be stored in EEPROM
•  Technology: Patented spread-spectrum charge-transfer (direct mode)
•  Key Outline Sizes: 6 mm × 6 mm or larger (panel thickness dependent); widely different sizes and shapes possible, including solid or ring shapes
•  Key Spacings:  7 mm center-to-center or more (panel thickness dependent)
•  Layers Required: One
• Electrode Materials: Etched copper, silver, carbon, Indium Tin Oxide (ITO)

• Consumer and industrial applications, such as TV, media player
