Product Details

The analog output ADXL356 and the digital output ADXL357 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 supports the ±10 g, ±20 g, and ±40 g ranges.

The ADXL356/ADXL357 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 enables accurate tilt measurement in an environment with high vibration. The low noise of the ADXL356 over higher frequencies is ideal for condition-based monitoring and other vibration sensing applications.

The ADXL357 multifunction pin names may be referenced only by their relevant function for either the serial peripheral interface (SPI) or limited I2C interface.

Applications

  • Inertial measurement units (IMUs)/altitude and heading reference systems (AHRSs)
  • Platform stabilization systems
  • Structural health monitoring
  • Seismic imaging
  • Tilt sensing
  • Robotics
  • Condition monitoring
