The QT401 QSlide™ IC is a 1-dimensional position sensor IC designed for human interfaces. This unique IC allows designers

to create speed or volume controls, menu bars, and other more exotic forms of human interface on the panel of an appliance

or over an LCD display.

The device uses a simple, inexpensive resistive sensing strip between two connection end points. The strip element can be an

arc or a semicircle or simply linear. The strip can also be used as a proximity sensor out to several centimeters, to wake up an

appliance or display from a sleep mode in a dramatic fashion.

The QT401 can report a single rapid touch anywhere along the slider element, or, it can track a finger moving laterally along

the slider strip in real time. The device self-calibrates under command from a host controller in one of two modes.

The QT401 is a new type of capacitive sensor based on Quantum’s patented charge-transfer methods. This device uses two

channels of simultaneous sensing across a resistive element to determine finger position, using mathematical analysis. The

accuracy of QSlide™ is theoretically the same as a conventional potentiometer. A positional accuracy of 5% (or better) is

relatively easy to achieve.

The acquisitions are performed in a burst mode which uses proprietary spread-spectrum modulation for superior noise

immunity and low emissions.

The output of the QT401 can also be used to create discrete controls on a strip, by interpreting sets of number ranges as

buttons. For example, the number range 0..19 can be button A, 30..49 button B, 60..79 button C etc. Continuous slider action

and discrete controls can be mixed on a single strip, or, the strip can be reinterpreted differently at different times, for example

when used below or on top of an LCD to act as a menu input device that dynamically changes function in context. In this

fashion the QT401 can be used to create ultra-simple, extremely inexpensive ‘touch screens’. The device is compatible with

ITO (Indium Tin Oxide) overlays on top of various displays.
