lQ 6 KEY CHARGE-TRANSFER QTOUCH SENSOR IC QProx QT160 / QT161 6 completely independent touch circuits Individual logic outputs per channel (active high) Projects prox fields through any dielectric Only one external capacitor required per channel Sensitivity easily adjusted on a per-channel basis 100% autocal for life - no adjustments required 3-5.5V, 5mA single supply operation Toggle mode for on/off control (strap option) 10s, 60s, infinite auto-recal timeout (strap options) AKS Adjacent Key Suppression (QT160) Less expensive per key than many mechanical switches Eval board with backlighting - p/n E160 NOTE: Pinouts are not the same! APPLICATIONS PC Peripherals Backlighted buttons Appliance controls Security systems Access systems Pointing devices Instrument panels Gaming machines QT160 / QT161 charge-transfer (“QT’”) QTouch ICs are self-contained digital controllers capable of detecting near-proximity or touch from up to 6 electrodes. They allow electrodes to project 6 independent sense fields through any dielectric like glass, plastic, stone, ceramic, and wood. They can also make metal-bearing objects responsive to proximity or touch by turning them into intrinsic sensors. These capabilities coupled with continuous self-calibration can lead to entirely new product concepts, adding high value to product designs. Each of the 6 channels operate independently of the others, and each can be tuned for a unique sensitivity level by simply changing its sample capacitor value……
