3轴、±2 G/±4 G/±8 G/±16 G数字加速度计

ADXL345是一款小而薄的低功耗三轴加速度计，可对高达±16g的加速度进行高分辨率（13位）测量。数字输出数据为16位二进制补码格式，可通过SPI（3线式或4线式）或I2C数字接口访问。\n\n ADXL345非常适合移动设备应用。它可以在倾斜检测应用中测量静态重力加速度，还可以测量运动或冲击导致的动态加速度。其高分辨率(4 mg/LSB)能够测量不到1.0°的倾角变化。\n\n 该器件提供多种特殊检测功能。活动和非活动检测功能通过比较任意轴上的加速度与用户设置的阈值来检测有无运动发生。敲击检测功能可以检测任意方向的单振和双振动作。自由落体检测功能可以检测器件是否正在掉落 • 低功耗：VS = 2.5 V（典型值）时，测量模式下低至23 μA，待机模式下低至0.1 μA\n\n• 功耗随带宽自动按比例变化\n\n• 用户可选的分辨率\n• 10位固定分辨率\n\n• 全分辨率，分辨率随g范围提高而提高，±16 g时高达13位（在所有g范围内保持4 mg/LSB的比例系数）\n\n\n\n\n• 嵌入式存储器管理系统采用FIFO技术，可充分降低主机处理器负荷\n\n• 单振/双振检测\n\n• 活动/非活动监控\n\n• 自由落体检测\n\n• 电源电压范围：2.0 V至3.6 V\n\n• I/O电压范围：1.7 V至VS\n\n• SPI（3线式和4线式）和I;
