ADXL373BCCZ-RL7

ADXL373 is an ultra low power, 3-axis, ±400 g microelectromechanical systems (MEMS) accelerometer. This does not power cycle its front end to achieve its low power operation and therefore does not run the risk of aliasing the output of the sensor. In addition to its ultra low power consumption, the ADXL373 enables impact detection while providing system level power reduction. Two additional lower power modes with interrupt driven, wake-up features are available for monitoring motion during periods of inactivity. In wake-up mode, acceleration data can be averaged to obtain a low enough output noise to trigger on low g thresholds. In instant on mode, the ADXL373 consumes 1.4μA while continuously monitoring the environment for impacts. Application includes impact and shock detection, asset health assessment, portable internet of things (IoT) edge nodes, concussion and head trauma detection.
