The QT118H charge-transfer (“QT’”) touch sensor is a self-contained digital IC capable of detecting near-proximity or touch. It will

project a sense field through almost any dielectric, like glass, plastic, stone, ceramic, and wood. It 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 can lead to entirely new product concepts.

The device is designed specifically for human interfaces, like control panels, appliances, toys, lighting controls, or anywhere a

mechanical switch or button may be found; it 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.

The IC requires only a common inexpensive capacitor in order to function. Average power consumption is under 20µA in most

applications, allowing battery operation.

The QT118H employs digital signal processing techniques pioneered by Quantum, designed to make it 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 device includes 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 the health of the device.

By using the charge transfer principle, the IC delivers a level of performance clearly superior to older technologies in a highly

cost-effective package.
