The QT240 charge-transfer (“QT’”) QTouch IC is a self-contained digital sensor IC capable of detecting near-proximity or touch

on 4 electrodes. It allows electrodes to project independent sense fields through any dielectric like glass, plastic, stone,

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

This capability coupled with its 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. Two speeds are supported, one of which consumes only 90µA of typical current at 4V.

Unique among capacitance sensors, the device incorporates spread spectrum modulation for unsurpassed EMC compliance.

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 feature a SYNC pin which allows for synchronization with additional similar parts and/or to an external source to

suppress interference. This pin doubles as a drive pin for spread-spectrum modulation. Option pins are provided which allow

different timing and feature settings.

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.
