ADI Delivers Ultra-Low Power MEMS Accelerometers for Healthcare and Industrial Applications

ADI has introduced a triaxial MEMS accelerometer that can be used in a wide range of healthcare and industrial applications, the

devices including vital signs monitoring, hearing assistance and motion metering.The ADXL367 accelerometer, compared to the previous generation device (ADXL362), has

The ADXL367 accelerometer offers a two-fold improvement in power consumption and more than 30 percent improvement in noise performance over its predecessor (ADXL362). The new accelerometers also offer longer in-field use, maximising battery life

maximising battery life and reducing maintenance frequency and cost.

The ADXL367 consumes only 0.88 μA at 100 Hz output data rate and 180 nA in motion-triggered wake-up mode.

Unlike accelerometers that use a power duty cycle to achieve low power consumption, the ADXL367 does not alias the input signal by undersampling, but instead samples the entire bandwidth of the sensor at the full data rate.

ADXL367 Key Features:

Motion detection power consumption of 200 nW in wake-up mode and 970 nW in measurement mode.

Deeper multi-mode output FIFOs, built-in micro-power temperature sensor, internal ADC for simultaneous conversion of additional analogue inputs, single/double click detection and state machine to prevent false triggering.

Supply voltage as low as 1.1V, running on a single battery, no external boost converter required.

Supports external control of sample time and/or external clock.

Rich digital features such as single and double clicks, drop detection, activity detection, etc. reduce computational requirements on the host microprocessor and further reduce system power consumption.
