DescriptionQuantum Research Group QPROX QT310-D User Programmable Advanced Sensor IC, 8-pin DIP PackageThe QT310 charge-transfer (“QT’”) touch sensor IC is a self-contained digital IC capable of detecting proximity, touch, or fluid level when connected to a corresponding type of electrode. It projects sense fields through almost any dielectric, like glass, plastic, stone, ceramic, and wood. It can also turn metal-bearing objects into intrinsic sensors, making them respond to proximity or touch. This capability coupled with its ability to self calibrate continuously or to have fixed calibration by example can lead to entirely new product concepts.It is designed specifically for advanced human interfaces like control panels and appliances or anywhere a mechanical switch or button may be found; it can also be used for material sensing and control applications, and for point-level fluid sensing. The ability to daisy-chain the ICs permits the construction of high-sensitivity controls where the electrodes of two or more QT310’s are adjacent to each other.The burst rate can be programmed to a wide variety of settings, allowing the designer to trade off power consumption for response time. The device requires only a common inexpensive external capacitor.The IC’s RISC core employs signal processing techniques pioneered by Quantum; these are specifically designed to make the device survive real-world challenges, such as ‘stuck sensor’ conditions and signal drift. All key operating parameters can be set by the designer via the internal eeprom which can be configured via Quantum’s cloning process to alter sensitivity, drift compensation rate, max on-duration, output polarity, calibration mode, Heartbeat™ feature, and toggle mode. No external switches, opamps, or other analog components aside from Cs are required.The Quantum-pioneered HeartBeat™ signal is also included, allowing a host controller to monitor the health of the QT320 continuously if desired. By using the charge transfer principle, the IC delivers a level of performance clearly superior to older technologies in a highly cost-effective package.
