ADXL288屬于傳感器變送器的運動傳感器-加速計。由亞德諾半導體技術有限公司制造生產(chǎn)的ADXL288運動傳感器 - 加速計加速度計用于檢測并響應運動或振動等加速度的變化。加速度計類型有 X、Y 或 Z 軸上的模擬或數(shù)字加速度計，加速度范圍為 ±0.5 g 至 ±2000 g，靈敏度為 1 至 500 k (LSB/g)，輸出類型有模擬電壓、藍牙、數(shù)字、DSI、IEPE、I2C、PCM、PWM、射頻和 SPI。

GENERAL DESCRIPTION

The ADXL288 is a dual-axis accelerometer with signal conditioned outputs available via a 16-bit SPI interface. Identical, independent X and Y sense structures are implemented to create a high performance, high integrity acceleration sensing system. The X and Y acceleration channels have a nominal full-scale range of ±120 g and a bandwidth of 408 Hz. The acceleration data is provided as a 12-bit, twos complement word with a resolution of 62.5 mg/LSB.
