LQ QPROX™ QT310 PROGRAMMABLE CAPACITANCE SENSOR IC Single channel digital advanced capacitance sensor IC Spread spectrum burst modulation for high EMI rejection Full autocal capability User programmable via cloning process Internal eeprom storage of user setups, cal data Variable drift compensation & recalibration times BG and OBJ cal modes for learn-by-example Sync pins for daisy-chaining or noise suppression Variable gain via Cs capacitor change Selectable output polarity, high or low Toggle mode (optional via setups) Push-pull output Completely programmable output behavior via cloning process from a PC HeartBeat™ health indicator (can be disabled) APPLICATIONS Fluid level sensors Industrial panels Appliance controls Security systems Access controls Material detection Micro-switch replacement Toys & games This device requires only a few external passive parts to operate. It uses spread-spectrum burst modulation to dramatically reduce interference problems. The 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 t...
