... PC Peripherals Backlighted buttons QT160 / QT161 charge-transfer (“QT’”) QTouch ICs are self-contained digital controllers capable of detecting near-proximity or touch from electrodes. They allow electrodes to project 6 independent sense fields through any dielectric like glass, plastic, stone, ceramic, and wood. They can also make metal-bearing objects responsive to proximity or touch by turning them into intrinsic sensors ...

OVERVIEW QT160/161 is a 6-channel burst mode digital charge-transfer (QT) sensor designed specifically for touch controls; they include all hardware and signal processing functions necessary to provide stable sensing under a wide variety of conditions. Only a single ...

Figure 1-2 Internal Switching & Timing Result Start not propagate fields laterally very well, and will have poor sensitivity in the middle. Experimentation is required. Since the channels acquire their signals in time-sequence, any of the 6 ...

... Vss, so that it lights when the sensor is active. 2.3 AKS™ - Adjacent Key suppression The QT160 (not QT161) features adjacent key suppression for use in applications where keys are tightly spaced. If keys are very close and a large finger touches one key, the keys on either side might also activate ...

ESD PROTECTION In cases where the electrode is placed behind a dielectric panel, the IC will be protected from direct static discharge. However even with a panel, transients can still flow into the electrodes via induction extreme ...
