Overview

The ADXL355BEZ-RL7 is a high-resolution, low-noise three-axis MEMS accelerometer designed for precision measurement applications. It features a 20-bit analog-to-digital converter and offers selectable measurement ranges of +/-2g, +/-4g, and +/-8g with an integrated temperature sensor and digital filters. The device is optimized for low-power operation, drawing minimal current while maintaining high stability over its full operating temperature range of -40 to 125 degrees Celsius.

Why Choose This Part

This sensor stands out for its exceptional noise density (22.5 micro-g/sqrt(Hz)), which enables high-resolution measurement of small vibrations. It offers versatility through both I2C and SPI digital interfaces and maintains consistent performance across a wide temperature range in a compact 14-CLCC package. The low power consumption and built-in sleep mode make it highly suitable for remote, battery-powered sensing nodes.

Applications

Inertial Measurement Units (IMUs)
Used in navigation and stabilization systems where low noise and high long-term stability are critical for orientation accuracy.
Structural Health Monitoring
Ideal for detecting micro-vibrations in bridges, buildings, and infrastructure due to its low noise floor and high resolution.
Seismic Sensing
Provides the sensitivity required for earthquake detection and volcanic activity monitoring.
Tilt Sensing
High-precision static tilt measurement for industrial leveling and platform positioning.

Getting Started

Engineers can evaluate the part using the EVAL-ADXL355Z evaluation board, which connects easily to a microcontroller via standard 0.1-inch headers. Communication is established by configuring the SPI or I2C bus to the sensor's registers; ensure the supply voltage is between 2.25V and 3.6V. Drivers and reference code for the ADXL355 family are available in the Analog Devices No-OS library and Linux IIO framework.
