The ADXL355 is a low noise, low power, 3-axis MEMS accelerometer with low zero-g offset drift and excellent alignment accuracy. It offers selectable measurement ranges of ±2.048 g, ±4.096 g, and ±8.192 g, delivering industry-leading noise performance, minimal misalignment drift, and long-term stability over temperature. These features enable precision sensing applications with reduced calibration requirements and extremely low power consumption. The ADXL355 achieves high-resolution vibration measurements with very low noise density, making it ideal for early detection of structural anomalies using wireless sensor networks. Its low power operation extends battery life and reduces the need for frequent battery replacement, supporting long-term deployment in cost-sensitive applications such as structural health monitoring (SHM). With superior tilt stability, the ADXL355 provides excellent repeatability across temperature and time, making it suitable for inclinometer and navigation systems in UAVs, inertial measurement units (IMUs), and other precision orientation systems. It maintains accurate tilt measurements in challenging environments without requiring extensive calibration. The device features a maximum zero-g offset temperature coefficient of 0.15 mg/°C, ensuring high temperature stability. This reduces the time and cost associated with system-level calibration and testing, supporting higher manufacturing throughput. Hermetically sealed packaging helps maintain long-term repeatability and stability after deployment. The ADXL355 offers a full-scale output range from ±2 g to ±8 g, configurable digital filtering from 1 Hz to 1 kHz, and a low noise density of 25 μg/√Hz.
