QT100A-ISGManufacturer: Atmel / Quantum Research This product is discontined.

It will project a touch or proximity field through any dielectric like glass, plastic, stone, ceramic, and even most kinds of wood. It can also turn small metal-bearing objects into intrinsic sensors, making them responsive to proximity or touch. This capability, coupled with its ability to self-calibrate, can lead to entirely new product concepts. It is designed specifically for human interfaces, like control panels, appliances, toys, lighting controls, or anywhere a mechanical switch or button may be found. Power consumption is around 600µA in most applications when running in Fast response mode. This typically drops to 6-12µA at 2V Vdd in Low Power mode, depending on the burst length. In most cases the power supply need only be minimally regulated; for example, by Zener diodes or an inexpensive three-terminal regulator. The QT100A only requires a common inexpensive X7R ceramic capacitor in order to function. The QT100A employs signal processing techniques pioneered by Quantum; these are specifically designed to make the device survive real-world challenges, such as 'stuck sensor' conditions and signal drift. The Quantum-pioneered HeartBeat™ signal is also included, allowing a microcontroller to monitor the health of the QT100A continuously, if desired. By using the charge transfer principle, the IC delivers a level of performance clearly superior to older technologies. Features
