The addition of two new devices have been announced to Analog Devices (ADI)’s popular series of low noise, low drift, low power, three-axis MEMS accelerometers. The low noise performance over high frequencies provided by the new ADXL356 and ADXL357 MEMS accelerometers delivers high resolution vibration measurements that enable the early detection of machine failure in condition monitoring applications.

This performance comes with very low power consumption, making the ADXL356 and ADXL357 suitable for wireless sensor networks. These new MEMSaccelerometers are also designed to provide accurate and reliable tilt measurements for environments high in shock and vibration without saturating the sensor, an important requirement for tilt measurement applications on heavy equipment or airborne platforms such as unmanned aerial vehicles (UAVs).  

The ADXL356 and ADXL357 MEMS accelerometers are the latest examples of high performance sensor technology from Analog Devices that provides high-quality data for Internet of Things (IoT) applications and enables intelligent sensing from the edge of the network.

The analogue output ADXL356 and the digital output ADXL357 three-axis accelerometers provide selectable measurement ranges of ±10, ±20 and ±40gfor greater flexibility. The ADXL356 and ADXL357 also offer industry leading noise density of 80µg/root Hz, with guaranteed maximum 0g offset drift over temperature of 0.75mg/C, enabling precision applications with minimal calibration.

In addition, the hermetic package helps ensure that the end product conforms to its repeatability and stability specifications long after it leaves the factory. Highly integrated in a compact form factor, the low power ADXL357 requires only 200uA, extending the life of battery powered applications including wireless networks for condition monitoring, airborne platforms such as UAVs or IoT applications.
