ADXL356 and ADXL357 MEMS accelerometers enable wireless condition monitoring

Two MEMS accelerometers have been added to the low noise, low drift, low power, three-axis MEMS accelerometers available from Analog Devices. The ADXL356 and ADXL357 provide low power vibration measurements for wireless condition monitoring.

The low noise performance over high frequencies of the ADXL356 and ADXL357 MEMS accelerometers delivers high resolution vibration measurements that enable the early detection of machine failure in condition monitoring applications, says Analog Devices. This performance uses little power, making the ADXL356 and ADXL357 particularly suitable for wireless sensor networks.

The ADXL356 and ADXL357 MEMS accelerometers are also designed to provide accurate and reliable tilt measurements for environments high in shock and vibration without saturating the sensor. This is 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 enable intelligent sensing from the edge of the network as well as Internet of things (IoT) applications.

 The analogue output ADXL356 and the digital output ADXL357, three-axis accelerometers provide selectable measurement ranges of ±10, ±20 and ±40g. Both the ADXL356 and ADXL357 offer what is believed to be industry-leading noise density of 80-micro g/root Hz, with guaranteed maximum 0g offset drift over temperature of 0.75mg/degree C, enabling precision applications with minimal calibration, says Analog Devices. The hermetically sealed, 14-lead, 6.0 x 6.0mm LCC package helps ensure that the end product conforms to its repeatability and stability specifications for a long period of time after it leaves the factory. The integrated, low power ADXL357 requires only 200-microA, extending the life of battery powered applications including wireless networks for condition monitoring, airborne platforms such as UAVs or IoT applications, says Analog Devices.
