ADXL354传感器变送器的运动传感器-加速计规格书PDF中文资料

ADXL354属于传感器变送器的运动传感器-加速计。由亚德诺半导体技术有限公司制造生产的ADXL354运动传感器 - 加速计加速度计用于检测并响应运动或振动等加速度的变化。加速度计类型有 X、Y 或 Z 轴上的模拟或数字加速度计，加速度范围为 ±0.5 g 至 ±2000 g，灵敏度为 1 至 500 k (LSB/g)，输出类型有模拟电压、蓝牙、数字、DSI、IEPE、I2C、PCM、PWM、射频和 SPI。

GENERAL DESCRIPTION

The analog output ADXL354 and the digital output ADXL355 are low noise density, low 0 g offset drift, low power, 3-axis accelerometers with selectable measurement ranges. The ADXL354B supports the ±2 g and ±4 g ranges, the ADXL354C supports the ±2 g and ±8 g ranges, and the ADXL355 supports the ±2.048 g, ±4.096 g, and ±8.192 g ranges. The ADXL354/ADXL355 offer industry leading noise, minimal offset drift over temperature, and long term stability enabling precision applications with minimal calibration.
