GENERAL DESCRIPTION
The the digital output ADXL357 is low noise density, low 0 g offset drift, low power, 3-axis accelerometers with selectable measurement ranges.The ADXL357BEZ supports the ±10.24 g, ±20.48 g, and ±40.96 g ranges.
The ADXL357BEZ offers 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 ADXL357BEZ enables accurate tilt measurement in an environment with high vibration, such as airborne IMUs.
The ADXL357BEZ multifunction pin names may be referenced only by their relevant function for either the SPI or limited I 2 C interface.
