The QT310 charge-transfer ("QT'") touch sensor IC is a self-contained digital IC capable of detecting proximity, touch, or fluid level when connected to a corresponding type of electrode. It projects sense fields through almost any dielectric, like glass, plastic, stone, ceramic, and wood. It can also turn metal-bearing objects into intrinsic sensors, making them respond to proximity or touch. This capability coupled with its ability to self calibrate continuously or to have fixed calibration by example can lead to entirely new product concepts. It is designed specifically for advanced human interfaces like control panels and appliances or anywhere a mechanical switch or button may be found; it can also be used for material sensing and control applications, and for point-level fluid sensing. The ability to daisy-chain permits electrodes from two or more QT310's to be adjacent to each other without interference. The burst rate can be programmed to a wide variety of settings, allowing the designer to trade off power consumption for response time.
