The AT42QT1011 is a digital burst mode charge-transfer sensor that is 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 centimetres 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.
- Configurable as either a single key or a proximity sensor
- Patented spread spectrum charge-transfer technology
- Key sensitivity can be set via a capacitor
