Introduction

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 ± 2g and ± 4g ranges, the ADXL354C supports the ± 2g and ± 8g ranges, and the ADXL355 supports the ± 2.048g, ± 4.096g, and ± 8.192g ranges. The ADXL354/ADXL355 offer industry leading noise, minimal offset drift over temperature, and long term stability enabling precision applications with minimal calibration.
