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

– 32-pin 5 x 5 mm MLF RoHS compliant

– 32-pin 7 x 7 mm TQFP RoHS compliant

– Portable devices, domestic appliances and A/V gear, PC peripherals, office equipment
