Features

ywhere a mechanical switch or button may be found. Power consumption is less than 500µA in most applications when running in Fast response mode. This typically drops to 5-10µA at 2V VDD in Low Power mode, depending on the burst length. In most cases the power supply need only be minimally regulated; for example, by Zener diodes or an inexpensive three-terminal regulator. The QT100 only requires a common inexpensive X7R ceramic capacitor in order to function. The QT100’s Reduced Instruction Set Computer ( RISC) core employs signal processing techniques pioneer ed by Quantum; these are specifica.
