Product Overview

E1081 KIT is designed for the evaluation and development of applications using the QT1081-ISG integrated circuit. The QT1081 is an improved, lower cost, simplified circuit sensor IC. QTouch technology is a type of patented charge transfer sensing method well known for its robust, stable, EMC resistant characteristics. It is the only all digital capacitive sensing technology in the market today. QTouch sensors employ a single reference capacitor tied to two pins of the chip for each sensing key, a signal trace leads from one of the pins to the sensing electrode which forms the key. The sensing electrode can be a simple solid shape such as a rectangle or circle. An LED can be placed near or inside the solid circle for illumination. The key electrodes can be designed into a conventional printed circuit board (PCB) or flexible printed circuit board (FPCB) as a copper pattern, or as printed conductive ink.
  • Patented spread spectrum charge transfer (one per key mode)
  • Simplicity, reliability, ease of design and cost effectiveness
  • Single solid or ring shaped electrodes; wide variety of possible layouts
  • Key sensitivity is settable via change in reference capacitor (Cs) value
  • Signal Processing: self calibration, auto drift compensation, noise filtering, patented AKS
