ADI provides ultra-low power MEMS accelerometer for medical health and industrial applications

     Analog Devices, Inc introduced a three-axis MEMS accelerometer, which can be used in a wide range of medical, health and industrial applications, including vital sign monitoring, hearing assistance, motion measurement and other equipment. Compared with the previous generation device (ADXL362), the ADXL367 accelerometer has twice the power consumption and more than 30% improvement in noise performance. The new accelerometer also provides longer field service time, maximizes battery life, and reduces maintenance frequency and cost.

     The power consumption of ADXL367 is only 0.88 µ A at 100 Hz output data rate, and 180 nA in motion triggered wake-up mode. Unlike accelerometers that use power duty cycle to achieve low power consumption, the ADXL367 does not use undersampling to mix input signals, but uses full data rate to sample the entire bandwidth of the sensor.
