描述 Description

The QT113 charge-transfer (“QT’”) touch sensor is a self-contained digital IC capable of detecting near-proximity or touch. It will project a proximity sense field through air, via almost any dielectric, like glass, plastic, stone, ceramic, and most kinds of wood. It can also turn small metal-bearing objects into intrinsic sensors, making them responsive to proximity or touch. This capability coupled with its ability to self calibrate continuously can lead to entirely new product concepts.
? Projects a proximity field through air
? Less expensive than many mechanical switches
? Sensitivity easily adjusted via capacitor value
? Turns small objects into intrinsic touch sensors
? 100% autocal for life - no adjustments required
? 2.5 to 5V, 600μA single supply operation
? Toggle mode for on/off control (strap option)
? 10s, 60s, infinite auto-recal timeout (strap options)
? Gain settings in 2 discrete levels
? HeartBeat? health indicator on output
? Active-low (QT113) or active-high outputs (QT113H)
? Only one external part required - a 1￠ capacitorAPPLICATIONS -
? Elevator buttons
? Toys & games
? Access systems
? Pointing devices
? Appliance control
? Security systems
? Light switches
? Prox sensors

簡介

QT113屬于集成電路（IC）的傳感器電容式觸控。由制造生產(chǎn)的QT113傳感器，電容式觸控該系列產(chǎn)品提供操作電容式觸摸感應(yīng)傳感器所需的模擬激勵和測量資源，并以一種便于微控制器或類似器件使用的格式（例如 I2C 或 SPI 串行接口、UART 或簡單的邏輯信號）來傳遞由此產(chǎn)生的信息。這些器件常用于人機(jī)界面應(yīng)用。
