OVERVIEW

QT140/150 devices are burst mode digital charge-transfer (QT) sensor ICs designed specifically for touch controls; they include all hardware and signal processing functions necessary to provide stable sensing under a wide variety of conditions. Only a single low cost capacitor per channel is required for operation.

â— Completely independent QT touch circuits

â— Individual logic outputs per channel (open drain)
â— Projects prox fields through any dielectric
â— Only one external capacitor required per channel
â— Sensitivity easily adjusted on a per-channel basis
â— 100% autocal for life - no adjustments required
â— 3~5.5V, 5mA single supply operation
â— Toggle mode for on/off control (strap option)
â— 10s, 60s, infinite auto-recal timeout (strap options)
â— AKSâ„¢ Adjacent Key Suppression (pin option)
â— Sync pin for multi-chip sync or line sync
â— Less expensive per key than many mechanical switches
â— Eval board with backlighting - p/n E160
