GENERAL DESCRIPTION

The analog output ADXL354 and the digital output ADXL355 are low noise density, low 0 g offset drift, low power, 3-axis accelerometers with selectable measurement ranges. The ADXL354B supports the ±2 g and ±4 g ranges, the ADXL354C supports the ±2 g and ±8 g ranges, and the ADXL355 supports the ±2.048 g, ±4.096 g, and ±8.192 g ranges. The ADXL354/ADXL355 offer industry leading noise, minimal offset drift over temperature, and long term stability enabling precision applications with minimal calibration.
