Typical Applications
ADXL357BEZ-RL7 is suitable for 6 applications: Inertial Navigation Systems, Structural Health Monitoring, Seismic Sensing, Vibration Monitoring, Tilt Sensing, Robotics and Autonomous Vehicles.
Inertial Navigation Systems
The ADXL357BEZ-RL7's low noise density of 80 µg/√Hz and low 0 g offset drift of 0.75 mg/°C make it ideal for inertial navigation systems where precise acceleration measurement is critical. Its selectable ranges up to ±40g accommodate dynamic maneuvers. The SPI interface allows high-speed data transfer to the navigation processor, and the low power consumption of 200 µA extends battery life in portable systems.
Recommended
Structural Health Monitoring
In structural health monitoring, the ADXL357BEZ-RL7 detects vibrations and tilts in bridges, buildings, and other infrastructure. Its low noise floor enables detection of small amplitude vibrations, while the wide temperature range (-40°C to +125°C) ensures reliable operation in outdoor environments. The device's low drift over temperature reduces the need for frequent recalibration, making it suitable for long-term monitoring installations.
Recommended
Seismic Sensing
The ADXL357BEZ-RL7 is well-suited for seismic sensing applications such as earthquake detection and oil exploration. Its low noise density of 80 µg/√Hz allows detection of very small ground motions, and the selectable ranges up to ±40g can capture strong seismic events without saturation. The device's low power consumption is advantageous for remote sensor nodes that operate on battery power.
Recommended
Vibration Monitoring
For industrial vibration monitoring, the ADXL357BEZ-RL7 provides high bandwidth up to 1 kHz, enabling detection of machinery faults such as bearing wear and imbalance. Its low noise and high resolution allow early detection of subtle changes in vibration signatures. The device's robust package and wide temperature range make it suitable for mounting on industrial equipment.
Recommended
Tilt Sensing
The ADXL357BEZ-RL7 can be used for tilt sensing in applications such as platform leveling and antenna positioning. Its low 0 g offset drift ensures accurate angle measurement over time and temperature. The selectable ±10g range is ideal for tilt applications where gravity is the primary acceleration. The SPI/I2C interface simplifies integration with microcontrollers.
Recommended
Robotics and Autonomous Vehicles
In robotics and autonomous vehicles, the ADXL357BEZ-RL7 provides accurate acceleration feedback for motion control and navigation. Its wide measurement range up to ±40g can handle sudden impacts, while the low noise density ensures smooth control. The device's small 6x6 mm package is ideal for space-constrained designs, and the low power consumption is beneficial for battery-powered robots.

Key Differentiators
- Selectable measurement ranges up to ±40g (vs ADXL355BEZ)
- Digital output with SPI/I2C interface (vs ADXL354BEZ)
- Low noise density of 80 µg/√Hz (vs ADXL356BEZ)
Design Notes
Ensure a clean power supply for the ADXL357BEZ-RL7. Use a 0.1 µF ceramic capacitor close to the VDD pin and a 10 µF bulk capacitor. The device operates from 2.25 V to 3.6 V, and proper decoupling minimizes noise coupling into the accelerometer output.
For optimal performance, place the accelerometer on a rigid PCB section away from mechanical resonances. Use a solid ground plane under the device and avoid routing high-speed digital traces near the analog output. The CLCC package has an exposed pad that should be soldered to the ground plane for thermal and mechanical stability.
Do not exceed the absolute maximum supply voltage of 3.6 V. Ensure SPI lines are not driven above VDD. The device has an internal self-test feature that can be used to verify functionality during production. Also, note that the ADXL357B variant has limited I2C support, so verify interface compatibility.
