QT161-AS数据手册集成电路（IC）的传感器电容式触控规格书PDF

描述 Description

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.● 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
● Pb-Free package available (QT160-ASG)APPLICATIONS
