  • Number of QTouch Keys: 0 to 7, one slider or one wheel
  • Technology: Patented spread-spectrum charge-transfer
  • Key Outline Sizes: 5 mm x 5 mm or larger (panel thickness dependent); widely different sizes and shapes possible
  • Key Spacing: 6 mm or wider, center to center (panel thickness, human factors dependent)
  • Key Design: Single solid or ring shaped electrodes; wide variety of possible layouts
  • Wheel Size: Typically 30 - 50 mm diameter, resistively interpolated wheel up to 80 mm diameter, typical width 12 mm
  • Slider Size: Typically 50 - 100 mm length, typical width 12 mm
  • Slider/Wheel Electrode Design: Choice of spatially interpolated (resistorless) or resistively interpolated design; Slider can be an arc or other irregular shape
  • Layers Required: One layer substrate; electrodes and components can be on same side
  • Substrates: FR-4, low cost CEM-1 or FR-2 PCB materials; polyamide FPCB; PET films, glass
  • Electrode Materials: Copper, silver, carbon, ITO, virtually anything electrically conductive
  • Panel materials: Plastic, glass, composites, painted surfaces (nonconductive paints)
  • Adjacent Metal: Compatible with grounded metal immediately next to keys
  • Panel Thickness: For keys, up to 15 mm glass, 10 mm plastic (key size dependent); For slider/wheel, up to 4 mm glass, 3 mm plastic
  • Key Sensitivity: Adjustable via change in sampling capacitor (Cs) value
  • Interface: SPI @ 750 kHz, CHANGE and DRDY status indicator pins
  • Moisture Tolerance: Increased moisture tolerance based on hardware design and firmware tuning
  • Power: 2.0 V to 5.5 V
  • Signal Processing: Self-calibration, autodrift compensation, noise filtering, patented Adjacent Key Suppression (AKS)
