QT140 / QT150 charge-transfer (“QT’”) QTouch ICs are self-contained digital controllers capable of detecting near-proximity or

touch on 4 or 5 electrodes. They allow electrodes to project independent sense fields through any dielectric like glass, plastic,

stone, ceramic, and wood. They can also turn metal-bearing objects into intrinsic sensors, making them responsive to proximity

or touch. This capability coupled with their continuous self-calibration feature can lead to entirely new product concepts, adding

high value to product designs.

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

changing its sample capacitor value.

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.

These devices require only a common inexpensive capacitor per sensing channel in order to function. They also offer patent

pending AKS™ Adjacent Key Suppression which 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.

These devices also have a SYNC I/O pin which allows for synchronization with additional similar parts and/or to an external to

suppress interference.

The RISC core of these devices use signal processing techniques pioneered by Quantum which are designed to survive

numerous real-world challenges, such as ‘stuck sensor’ conditions, component ageing, moisture films, and signal drift.

By using the charge transfer principle, these devices deliver a level of performance clearly superior to older technologies yet

are highly cost-effective.
