QT1106 charge-transfer (‘QT’) QTouch
TM
IC is a self-contained, patented charge-transfer capacitive controller capable of
detecting near-proximity or touch on up to seven electrodes and a wheel. It allows electrodes to project sense fields through
any dielectric such as glass or plastic. These electrodes are laid out as a scroller (e.g. a wheel or slider) plus seven
additional independent keys. Each key channel can be tuned for a unique sensitivity level by simply changing a corresponding
external Cs capacitor, whereas the wheel/slider’s sensitivity can be changed dynamically through SPI commands.
The wheel/slider uses a simple, inexpensive sensing element between three connection points. The QT1106 can report a
single rapid touch anywhere along the sense elements, or it can track a finger moving along the wheel/slider’s surface in real
time.
The device is designed specifically for human interfaces, like control panels, appliances, gaming devices, lighting controls,
remote controls, or anywhere a mechanical wheel, slider, or switch may be found.
Patented AKS™ Adjacent Key Suppression suppresses touch from weaker responding keys and only allows a dominant key to
detect; for example, to solve the problem of large fingers on tightly spaced keys or buttons in the middle of a wheel.
By using the charge-transfer principle, this device delivers a level of performance clearly superior to older technologies yet
is highly cost-effective. Spread-spectrum burst technology provides superior noise rejection. The device also has a Sync mode
which enables synchronization with additional similar parts and/or to an external source to suppress interference, and low
power modes which conserve power.
