QT1106 charge-transfer (‘QT’) QTouch
charge-transfer capacitive controller capable of detecting near-proximity or
touch on up to seven electrodes and a wheel/slider. 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. One key can
even be optimized for operation as a hand proximity sensor by increasing the
proximity sensitivity for the corresponding channel.
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.
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.
