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 ±2gand ±4granges, the ADXL354C supports the ±2gand ±8granges, and the ADXL355 supports the ±2g, ±4g, and ±8granges. 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 serial peripheral interface (SPI) or I2C interface.ApplicationsInertial measurement units (IMUs)/altitude and heading reference systems (AHRS)Platform stabilization systemsStructural health monitoringSeismic imagingTilt sensingRoboticsCondition Monitoring
