Applications:
– 0 to 7, one slider or one wheel
– Patented spread-spectrum charge-transfer
– 5 mm x 5 mm or larger (panel thickness dependent); widely different sizes and
– 6 mm or wider, center to center (panel thickness, human factors dependent)
– Single solid or ring shaped electrodes; wide variety of possible layouts
– Typically 30 – 50 mm diameter, resistively interpolated wheel up to 80 mm diameter,
– Typically 50 – 100 mm length, typical width 12 mm
– Choice of spatially interpolated (resistorless) or resistively interpolated design
– Slider can be an arc or other irregular shape
– One layer substrate; electrodes and components can be on same side
– FR-4, low cost CEM-1 or FR-2 PCB materials; polyamide FPCB; PET films, glass
– Copper, silver, carbon, ITO, virtually anything electrically conductive
– Plastic, glass, composites, painted surfaces (nonconductive paints)
– Compatible with grounded metal immediately next to keys
– For keys, up to 15 mm glass, 10 mm plastic (key size dependent)
– For slider/wheel, up to 4 mm glass, 3 mm plastic
– Adjustable via change in sampling capacitor (Cs) value
– SPI @ 750 kHz, CHANGE and DRDY status indicator pins
– Good
– 2.0V ~ 5.5V
– Self-calibration, autodrift compensation, noise filtering, patented Adjacent Key
