Analog Devices ADXL357 digital accelerometer combines high performance, low noise, and power efficiency in a 3-axis design. Built for precision applications, this advanced MEMS sensor offers versatility through its selectable measurement ranges of ±10 g, ±20 g, and ±40 g. The exceptional thermal stability is demonstrated by a maximum 0 g offset drift of just 0.75 mg/°C, ensuring reliable performance across an operating temperature range of -40°C to +125°C. Performance is further emphasized by the accelerometer's ultra-low noise spectral density of 75 µg/√Hz, which guarantees precise measurements in demanding applications. Power efficiency remains a key strength, with the device consuming only 200 µA in measurement mode and dropping to a mere 21 µA in standby mode, making it an ideal choice for battery-dependent and power-sensitive applications.

The digital architecture of the ADXL357 incorporates several advanced features that enhance its capabilities. A high-resolution 20-bit ADC forms the core of its data acquisition system, while both digital SPI and I²C interfaces provide flexible connectivity options. Users can fine-tune signal processing through programmable high-pass and low-pass digital filters, as well as benefit from synchronous sampling via the integrated data interpolation routine. An onboard temperature sensor adds environmental monitoring capabilities to this rich feature set. The device offers flexible power options, operating on a supply voltage range of 2.25 V to 3.6 V, with the additional capability to bypass the internal regulator for 1.8 V operation.

Housed in a compact 14-terminal LCC package measuring just 6 mm x 5.6 mm x 2.2 mm, the ADXL357 is engineered for maximum stability and precision, particularly in environments with high vibration levels. This comprehensive feature set makes it the ideal choice for a wide range of applications, including inertial measurement units, platform stabilization systems, structural health monitoring, seismic imaging, tilt sensing, robotics, and condition-based monitoring systems. The combination of advanced measurement capabilities, power efficiency, and robust design makes the ADXL357 a great solution for applications demanding both precision and reliability.

The EVAL-ADXL357Z evaluation board allows quick evaluation of the performance of the ADXL357 MEMS accelerometers. It is easily attachable to a prototyping board or PCB and it contains two sets of spaced vias for populating 6-pin headers. The small size and board stiffness of the EVAL-ADXL357Z help to minimize acceleration measurements as well as impact on the system being monitored. Additionally, the accelerometer is included with the eval board and is soldered to the PCB.
