ADXL357B中文资料Low Noise, Low Drift, Low Power, 3-Axis MEMS Accelerometers数据手册ADI规格书

描述 Description

The analog output ADXL356 and the digital outputs ADXL357 and ADXL357B are low noise density, low 0 g offset drift, low power, 3-axis accelerometers with selectable measurement ranges. The ADXL356B supports the ±10 g and ±20 g ranges, the ADXL356C supports the ±10 g and ±40 g ranges, and the ADXL357 and ADXL357B support the ±10 g, ±20 g, and ±40 g ranges.
The ADXL356/ADXL357/ADXL357B1 offer industry leading noise, minimal offset drift over temperature, and long-term stability, enabling precision applications with minimal calibration.
The low drift, low noise, and low power ADXL357 and ADXL357B enable accurate tilt measurement. The ADXL357B is more robust/suitable for tilt sensing in high vibration environments. The low noise of the ADXL356 over higher frequencies is ideal for condition-based monitoring and other vibration sensing applications.
The ADXL357 and ADXL357B multifunction pin names may be referenced only by their relevant function for either the serial peripheral interface (SPI) or limited I2C interface.
