4 AND 5 KEY QTOUCH™ SENSOR ICs

QT140 / QT150 charge-transfer (QT) QTouch ICs are self-contained digital controllers capable of detecting near-proximity or touch on 4 or 5 electrodes. They allow electrodes to project independent sense fields through any dielectric like glass, plastic, stone, ceramic, and wood. They CAN also turn metal-bearing objects into intrinsic Sensors making them responsive to proximity or touch. This capability coupled with their continuous self-calibration feature CAN lead to entirely new product concepts, adding high value to product designs. By Quantum Research Group
