QT1101 charge-transfer (‘QT’) QTouch^TMIC is a self-contained, patented digital controller capable of detecting near-proximity or touch

on up to ten electrodes. It allows electrodes to project independent sense fields through any dielectric such as glass or plastic. This

capability coupled with its continuous self-calibration feature can lead to entirely new product concepts, adding high value to product

designs. The devices are designed specifically for human interfaces, like control panels, appliances, gaming devices, lighting controls,

or anywhere a mechanical switch or button may be found; they may also be used for some material sensing and control applications.

Each of the channels operates independently of the others, and each can be tuned for a unique sensitivity level by simply changing a

corresponding external Cs capacitor.

Patented AKS™ Adjacent Key Suppression suppresses touch from weaker responding keys and allows only a dominant key to detect,

for example to solve the problem of large fingers on tightly spaced keys.

Spread spectrum burst technology provides superior noise rejection. These devices also have a SYNC/LP pin which allows for

synchronization with additional similar parts and/or to an external source to suppress interference, or, an LP (low power) mode which

conserves power.

By using the charge transfer principle, this device delivers a level of performance clearly superior to older technologies yet is highly

cost-effective.
