QT113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

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

简介

QT113属于集成电路（IC）的传感器电容式触控。由制造生产的QT113传感器，电容式触控该系列产品提供操作电容式触摸感应传感器所需的模拟激励和测量资源，并以一种便于微控制器或类似器件使用的格式（例如 I2C 或 SPI 串行接口、UART 或简单的逻辑信号）来传递由此产生的信息。这些器件常用于人机界面应用。
