QT110 family QTouch™ ICs will create sense fields through dielectric surfaces such as plastic or glass up to 100mm (4") thick, and can even turn small objects into sensors. These sense fields can work easily through gloved hands.
These ICs are ideal for simple, inexpensive touch controls in almost any product. The QT113 and QT118H can also be used for material or moisture sensing. The devices require only an external sampling capacitor and an electrode to operate.
QT110 family devices offer auto calibration, drift compensation, recalibration timeouts, plus a variety of response times, output polarities and toggle modes. These parts need no special calibration or adjustment. They automatically adapt to the build-up of dirt, moisture, and temperature variations.
Sensitivity can be adjusted by changing the value of Cs, and/or via a gain pin.
Most QT110 family devices are designed for human touch. The QT110 and QT118H include piezo beeper drive logic (see selection table below). Current consumption is as low as 10µA.
