Analog Devices introduced a 3-axis, 200-g digital MEMS (micro-electro-mechanical systems) accelerometer with the highest bandwidth and lowest power in its class. The ADXL375 MEMS accelerometer continuously measures the duration and magnitude of impact or shock events within the full-scale range of ±200 g without saturation. The new sensor consumes 140 μA at a full bandwidth of up to 1,600 Hz, delivering more than twice the sampling rate of competing sensors at less than half the power. The ADXL375 is suited for low- and battery-powered wireless sensor networks used in concussion detection, transportation, asset tracking and other applications that are subject to sudden, high-magnitude forces.

ADXL375 enables next-generation Blast Gauge impact detection system

The ADXL375 has been designed into the newest generation of the Blast Gauge, a body-worn blast detection system developed by BlackBox Biometrics. The device is currently deployed with U.S. Armed Forces to measure and record concussive event data that is then used for health and safety assessment. The device also utilizes ADI’s ADXL362 low-power, 3-axis MEMS accelerometer as part of an intelligent, continuously operational, motion-activated switch to increase battery life in the sealed environment.

ADXL375 MEMS accelerometer features user-selectable impact threshold levels

The ADXL375 3-axis, 200-g MEMS accelerometer includes an integrated memory management system consisting of a 32-level FIFO (first-in, first-out) memory. The buffer memory includes low-power modes that can be used to set impact thresholds, store data and lower overall system power consumption by offloading those functions from the host processor.
