ADXL372BCCZ-RL7

ADXL372 is an ultralow power, 3-axis, ±200g MEMS accelerometer that consumes 22µA at a 3200Hz output data rate (ODR). The ADXL372 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 ultralow power consumption, the ADXL372 has many features to enable impact detection while providing system level power reduction. This device includes a deep multimode output first in, first out (FIFO), several activity detection modes, and a method for capturing only the peak acceleration of over threshold events. Application includes impact and shock detection, asset health assessment, portable Internet of Things (IoT) edge nodes, concussion and head trauma detection.

• Selectable oversampling ratio, adjustable high-pass filter
• Ultralow power, power can be derived from a coin cell battery
• Low power, wake-up mode for low g activity detection
• Built in features for system level power savings
• Autonomous interrupt processing without processor intervention
• Deep embedded FIFO to minimize host processor load
• Ability to capture and store peak acceleration values of events
• Acceleration sample synchronization via external trigger
• SPI digital interface and limited I²C interface format support
• 16-lead LGA package, temperature range from -40°C to +105°C
