GENERAL DESCRIPTION：

The analog output ADXL354 and the digital output ADXL3551 arelow noise density, low 0 g offset drift, low power, 3-axis accelerometers with selectable measurement ranges. The ADXL354B supportsthe ±2 g and ±4 g ranges, the ADXL354C supports the ±2 gand ±8 g ranges, and the ADXL355 supports the ±2 g, ±4 g,and ±8 g ranges. The ADXL354/ADXL355 offer industry leadingnoise, minimal offset drift over temperature, and long-term stabilityenabling precision applications with minimal calibration.Highly integrated in a compact form factor, the low power ADXL355is ideal in an Internet of Things (IoT) sensor node and otherwireless product designs.The ADXL355 multifunction pin names may be referenced by theirrelevant function only for either the serial peripheral interface (SPI)or I2C interface.
