　　用于消费者和工业应用的低功耗MEMS传感器

　　MEMS传感器彻底改变了我们与日常技术交互的方式，使它更容易和更方便用户使用。MEMS传感器提供的功能，如2和三轴线性加速度计以及单轴和多轴陀螺仪等制造商意法半导体现在推出的6D数字化地磁模块结合在一个单一的包一个3轴加速度计和三轴磁强计。

　　消费市场正推动着微型、廉价、低电压和低功耗器件的需求。

　　手持设备，如移动电话，MP3和MP4播放器，便携式PC都是电池供电，正在变得越来越薄。电源电压下降到1.8伏，电流必须小于100微米A。此外，用户已经期待一个掉电功能以及多个中断引脚功能，以简化最终消费品的产品集成。

　　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.
