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 ±± g ranges, and the ADXL355 supports

the ±2.04± g, ±4.096 g, and ±±.ꢀ92 g ranges. The ADXL354/

ADXL355 offer industry leading noise, minimal offset drift over

temperature, and long term stability enabling precision

applications with minimal calibration.

Highly integrated in a compact form factor, the low power

ADXL355 is ideal in an Internet of Things (IoT) sensor node

and other wireless product designs.

The ADXL355 multifunction pin names may be referenced by

their relevant function only for either the SPI or I²C interfaces.
