Typical Applications
ADXL357BEZ 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's low noise density (80 µg/√Hz) and low 0 g offset drift (±0.75 mg/°C) enable precise measurement of structural vibrations in bridges, buildings, and dams. Its selectable ranges up to ±40g allow detection of both small ambient vibrations and large seismic events. The digital SPI/I2C interface simplifies integration with data acquisition systems, and the wide temperature range (-40°C to +125°C) ensures reliable outdoor operation. The device's low power consumption (200 µA) supports battery-powered remote monitoring nodes.
Recommended
Condition Monitoring of Rotating Machinery
In industrial machinery, the ADXL357BEZ detects vibration signatures indicative of bearing wear, imbalance, or misalignment. Its bandwidth of 1 kHz covers common machine vibration frequencies, and the low noise floor allows early fault detection. The digital output enables direct connection to a DSP or MCU for real-time FFT analysis. The device's shock survival of 10000 g ensures robustness in harsh environments. With selectable ranges, it can monitor both low-speed and high-speed equipment without saturation.
Recommended
Inertial Measurement Units (IMUs)
The ADXL357BEZ is a key component in IMUs for navigation and stabilization systems. Its low noise and low drift ensure accurate velocity and position estimation over time. The device's digital interface allows easy fusion with gyroscopes and magnetometers. The selectable ranges accommodate different dynamic environments, from pedestrian navigation (±10g) to aerial platforms (±40g). The compact 6x6 mm CLCC package saves board space, and the low power consumption extends battery life in portable devices.
Recommended
Platform Stabilization
For camera gimbals, antenna positioning, and vehicle stabilization, the ADXL357BEZ provides the high-bandwidth, low-latency acceleration feedback needed for closed-loop control. Its 1 kHz bandwidth and low noise enable precise vibration compensation. The digital output simplifies interfacing with control processors, and the selectable ranges allow tuning to the specific platform dynamics. The device's low drift ensures stable operation over long missions, and its small footprint is ideal for space-constrained gimbal designs.
Recommended
Seismic Sensing
The ADXL357BEZ's ultra-low noise density (80 µg/√Hz) makes it suitable for seismic monitoring applications, detecting ground motion from earthquakes or volcanic activity. Its low 0 g offset drift ensures long-term stability for continuous monitoring. The wide dynamic range, provided by the 20-bit ADC and selectable ranges, allows detection of both microseisms and strong ground motion. The digital output facilitates networking of multiple sensors, and the low power consumption enables solar-powered remote stations.
Recommended
Tilt Sensing and Leveling
The ADXL357BEZ can measure static acceleration due to gravity, enabling tilt sensing with high resolution. Its low noise and low drift allow precise angle measurement over time. The selectable ranges let designers trade off resolution vs. measurement range; for tilt sensing, the ±10g range provides the highest sensitivity. The digital interface simplifies calibration and compensation. Applications include industrial leveling, antenna alignment, and robotics. The device's low power consumption is ideal for battery-operated tilt sensors.

Key Differentiators
- Low noise density of 80 µg/√Hz (vs ADXL355BEZ)
- Selectable measurement ranges up to ±40g (vs ADXL355BEZ)
- Digital output with SPI/I2C (vs ADXL356BEZ)
Design Notes
Provide a clean power supply to the ADXL357BEZ. Use a 0.1 µF ceramic capacitor close to the VDD pin and a 1 µF capacitor on the VDD_IO pin. A low-noise LDO such as the ADP150 is recommended to minimize supply noise, which can affect accelerometer performance.
Mount the ADXL357BEZ on a rigid PCB to avoid mechanical stress that can cause offset drift. Ensure the PCB is flat and free from warpage. Use a solid ground plane under the device and avoid routing high-speed signals near the sensor to reduce electromagnetic interference.
Do not exceed the absolute maximum ratings, especially the supply voltage (3.6V) and shock survival (10000 g). When using SPI, ensure the CS pin is properly controlled to avoid communication errors. For I2C, set the ASEL pin correctly to avoid address conflicts.
