The QT110 / QT110H charge-transfer (“QT’”) sensor chips are self-contained digital ICs used to implement near-proximity or touch

sensors. They project sense fields through almost any dielectric, like glass, plastic, stone, ceramic, and wood. They can also turn small

metal-bearing objects into intrinsic sensors, making them respond to proximity or touch. This capability coupled with an ability to

self-calibrate continuously leads to entirely new product concepts.

These devices are designed specifically for human interfaces, like control panels, appliances, toys, lighting controls, or anywhere a

mechanical switch or button may be found; they may also be used for some material sensing and control applications provided that the

presence duration of objects does not exceed the recalibration timeout interval.

A piezo element can also be connected to create a feedback click sound.

These ICs require only a common inexpensive capacitor in order to function. Average power consumption is under 20µA in most

applications, allowing battery operation.

The devices employ digital signal processing techniques pioneered by Quantum, designed to make them survive real-world challenges,

such as ‘stuck sensor’ conditions and signal drift. Sensitivity is digitally determined for the highest possible stability. No external active

components are required for operation.

The devices include several user-selectable built-in features. One, toggle mode, permits on/off touch control for example for light switch

replacement. Another makes the sensor output a pulse instead of a DC level, which allows the device to 'talk' over the power rail,

permitting a simple 2-wire twisted-pair interface. Quantum’s unique HeartBeat™ signal is also included, allowing a host controller to

continuously monitor sensor health.

By using the charge transfer principle, these ICs deliver a level of performance clearly superior to older technologies in a highly

cost-effective package.
