Typical Applications
ADXL357BEZ-RL is suitable for 6 applications: Structural Health Monitoring, Condition Monitoring of Rotating Machinery, Inertial Measurement Units (IMUs), Platform Stabilization, Seismic Sensing, Tilt Sensing and Leveling.
Structural Health Monitoring
The ADXL357BEZ-RL's low noise density of 80 µg/√Hz and wide bandwidth up to 1kHz make it ideal for detecting micro-vibrations in bridges, buildings, and other structures. Its low 0 g offset drift ensures accurate long-term measurements, while the selectable ranges allow adaptation to different vibration levels. The digital SPI/I2C interface simplifies integration with data acquisition systems, and the 32-level FIFO reduces host processor load during continuous monitoring.

Platform Stabilization
For camera gimbals and antenna stabilization, the ADXL357BEZ-RL provides precise tilt and vibration feedback. Its low noise density ensures smooth stabilization, and the wide bandwidth allows fast response to disturbances. The SPI interface enables high-speed control loops, while the FIFO reduces interrupt overhead. The device's low power consumption is beneficial for battery-operated gimbals, and the wide temperature range supports outdoor use.
Recommended
Seismic Sensing
The ADXL357BEZ-RL's ultra-low noise (80 µg/√Hz) and low drift make it suitable for seismic monitoring applications. It can detect ground motion with high resolution, aiding in earthquake early warning systems. The wide bandwidth captures both low-frequency and high-frequency seismic waves. The digital output allows direct connection to data loggers, and the low power consumption enables remote deployment with battery power. The device's robust package withstands harsh environmental conditions.

Key Differentiators
- Selectable measurement ranges up to ±40g (vs ADXL354BEZ)
- Digital output with SPI/I2C interface (vs ADXL354BEZ)
- Lower noise density than ADXL362 (vs ADXL362BCCZ)
Design Notes
The ADXL357BEZ-RL operates from 2.25V to 3.6V. Use a low-noise LDO such as the ADP150 to supply the sensor, and place a 0.1µF and 1µF decoupling capacitor close to the VDD pin. Avoid sharing the supply with high-current digital circuits to prevent noise coupling.
For optimal performance, place the accelerometer on a rigid PCB section away from flexural stress. Use a solid ground plane under the device and route the SPI/I2C lines with controlled impedance if long. Ensure the CLCC package's exposed pad is soldered to the ground plane for thermal and mechanical stability.
Do not exceed the absolute maximum supply voltage of 3.6V. When using I2C, ensure pull-up resistors are connected to the correct voltage level. The FIFO can be configured to reduce interrupt load; set the watermark level appropriately to avoid data loss. Also, calibrate the 0 g offset at the system level for best accuracy.
