用于消費(fèi)者和工業(yè)應(yīng)用的低功耗MEMS傳感器

　　MEMS傳感器徹底改變了我們與日常技術(shù)交互的方式，使它更容易和更方便用戶使用。MEMS傳感器提供的功能，如2和三軸線性加速度計以及單軸和多軸陀螺儀等制造商意法半導(dǎo)體現(xiàn)在推出的6D數(shù)字化地磁模塊結(jié)合在一個單一的包一個3軸加速度計和三軸磁強(qiáng)計。

　　消費(fèi)市場正推動著微型、廉價、低電壓和低功耗器件的需求。

　　手持設(shè)備，如移動電話，MP3和MP4播放器，便攜式PC都是電池供電，正在變得越來越薄。電源電壓下降到1.8伏，電流必須小于100微米A。此外，用戶已經(jīng)期待一個掉電功能以及多個中斷引腳功能，以簡化最終消費(fèi)品的產(chǎn)品集成。

　　Ultra-low power 3-axis accelerometers

　　MEMS accelerometer portfolios have been extended with a new 3-axis digital-output accelerometer that has a significant 90 percent power reduction compared to currently available solutions on the market. They also feature a miniature footprint and enhanced functionalities. With operating current consumption as low as 2 μA， the 3 mm x 3 mm x 1 mm accelerometer is a perfect fit for motion-sensing features and applications in space- and power-constrained consumer devices such as mobile phones， games， and remote controllers.

　　The sensor provides accurate output across selectable full-scale ranges of ±2g/±4g/±8g/±16g with excellent offset and sensitivity stability over time and temperature.
