Description
AI
The analog output ADXL356 and the digital outputsADXL357and ADXL357B are low noise density, low 0goffset drift, low power, 3-axis accelerometers with selectable measurement ranges. The ADXL356B supports the ±10gand ±20granges, the ADXL356C supports the ±10gand ±40granges, and the ADXL357 and ADXL357B support the ±10g, ±20g, and ±40granges.The ADXL356/ADXL357/ADXL357B1offer 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.ApplicationsInertial measurement units (IMUs)/altitude and heading reference systems (AHRSs)Platform stabilization systemsStructural health monitoringSeismic imagingTilt sensingRoboticsCondition monitoring
