The ADXL355 is a low noise, low power, 3-axis MEMS accelerometer with selectable measurement ranges. It supports ±2.048g, ±4.096g, and ±8.192g full-scale ranges, delivering industry-leading noise performance, minimal misalignment drift, and excellent long-term stability over temperature. This enables precision applications with reduced calibration requirements and extremely low power consumption. The ADXL355 provides high-resolution vibration measurements with very low noise density, allowing early detection of structural anomalies using wireless sensor networks. Its low power operation extends battery life and reduces the need for frequent battery replacements, supporting longer product lifecycles. The combination of low noise and low power performance makes it suitable for cost-effective implementation of low-level vibration monitoring applications such as structural health monitoring (SHM). The device offers strong tilt stability with excellent repeatability over time and temperature, making it ideal for directional and navigation systems in UAVs, inertial measurement units (IMU), and inclinometers. It delivers reliable tilt measurements in various environments and minimizes errors in challenging conditions without requiring extensive calibration. The ADXL355 features temperature stability with a maximum zero g bias shift of 0.15 mg/°C, reducing the time and cost associated with testing and calibration. Hermetically sealed packaging ensures long-term repeatability and stability after deployment. The accelerometer offers a full-scale range from ±2g to ±8g, configurable digital filtering from 1 Hz to 1 kHz, and a low noise density of 25 μg/√Hz.
