The digital outputs ADXL357B are low noise density, low 0 g offset drift, low power, 3-axis accelerometers with selectable measurement ranges. The ADXL357B support the ±10 g, ±20 g, and ±40 g ranges.

The ADXL357B 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 ADXL357B enable accurate tilt measurement. The ADXL357B is more robust/suitable for tilt sensing in high vibration environments.

The ADXL357B multifunction pin names may be referenced only by their relevant function for either the serial peripheral interface (SPI) or limited I²C interface.
