AT42QT1010-MAH Datasheet PDF - Microchip

The AT42QT1010-MAH is a single-key QTouch® digital burst mode charge-transfer Touch Sensor IC capable of detecting near proximity or touch, making it ideal for implementing touch controls. With the proper electrode and circuit design, the self-contained digital IC will project a touch or proximity field to several centimeters 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. The QT1010 is designed specifically for human interfaces, like control panels, appliances, toys, lighting controls or anywhere a mechanical switch or button may be found. It includes all hardware and signal processing functions necessary to provide stable sensing under a wide variety of changing conditions.
