The ADXL367 is an ultra-low power, 3-axis microelectromechanical systems (MEMS) accelerometer that consumes only 0.89 μA at a 100 Hz output data rate and 180 nA when in motion-triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL367 does not alias input signals by under sampling, but samples the full bandwidth of the sensor at all data rates.
Key Features and Benefits
- Enables true system-level power reduction with single-cell battery operation from 1.1V to 3.6V
- Integrated, power-saving digital features including single-tap and double-tap detection, and adjustable threshold sleep and wake-up modes for motion activation
- Available in small 2.2 mm x 2.3 mm packaging
Applications
- Healthcare: Hearing aids, defibrillators, pacemakers, cardiac monitors, VSM
- Consumer: Fitness trackers, earbuds, luxury watches
- Industrial Automation: Asset monitoring, livestock monitoring, battery health, building safety, tamper detection, event logger, motion switch, IoT
- Automotive: Key fobs, battery health, event data recorders
Evaluation Board
The ADXL367 can be evaluated with the EVAL-ADXL367-SDP.
