ADI ADXL357BEZ-RL7

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 ± 10g and ± 20g ranges, the ADXL356C supports the ± 10g and ± 40g ranges, and the ADXL357 supports the ± 10g, ± 20g, and ± 40g 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.
