• Stable operation over a wide temperature range: It maintains stable performance in extreme temperatures from -40°C to 125°C, adapting to harsh environments such as industrial and aerospace fields .

Technical Specifications

Typical Applications

• In inertial measurement units (IMUs) and attitude heading reference systems (AHRSs), the low noise and high resolution of ADXL357BEZ can accurately capture the motion attitude of objects. Combined with its wide measurement range, it provides stable position and attitude data for drones and autonomous driving equipment, ensuring navigation accuracy.
• In structural health monitoring, ADXL357BEZ can sensitively detect tiny vibrations of buildings, bridges, and other structures. Its 75μg/√Hz low noise performance enables it to identify early structural damage signals, and its wide temperature operating capability ensures long-term reliable operation in complex outdoor environments.
• Robotics control systems rely on accurate acceleration feedback for smooth movement. ADXL357BEZ supports multi-interface integration, enabling rapid transmission of acceleration data to the controller. Meanwhile, its low power consumption design reduces the battery burden of robots and extends their continuous working time.
• Seismic imaging requires capturing weak ground vibration signals. The ultra-low noise characteristics of ADXL357BEZ can reduce signal interference, and its wide measurement range can detect both tiny tremors and strong earthquake shocks, providing high-quality data for geological research.
• In platform stabilization systems (such as satellite antennas and optical equipment), ADXL357BEZ can real-time monitor platform tilt and vibration, drive adjustment mechanisms through fast data output, offset external interference, and ensure the platform remains stable. It is particularly suitable for use in environments with drastic temperature changes.

Why Choose ADXL357BEZ?

• High-precision data output: The 20-bit ADC ensures measurement resolution, which is approximately 16 times higher than that of 16-bit ADC products, meeting the needs of precision detection .
• Excellent noise control: With a noise spectral density of 75μg/√Hz, it is 25% lower than similar medium-high noise products (e.g., 100μg/√Hz), significantly improving weak signal detection capability .
• Flexible power management: Supports internal LDO regulator (2.25V-3.6V) and external power supply modes, adapting to different system power designs and enhancing compatibility .
• Comprehensive filtering functions: Built-in programmable high-pass and low-pass digital filters, which can adjust bandwidth according to application scenarios (such as vibration monitoring, tilt sensing) to reduce invalid signal interference .
• Long-term stability guarantee: The hermetic package design ensures that the maximum 0g offset temperature drift is only 0.75mg/°C. After 1000-hour high-temperature aging test, the failure rate is less than 0.1%, suitable for long-term deployment .
