ADXL371BCCZ-RL7

ADXL371 is an ultra low power, 3-axis, ±200 g microelectromechanical system (MEMS) accelerometer that consumes 28µA at a 2560Hz output data rate (ODR). 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 ADXL371 enables impact detection while providing system level power reduction. The 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. Two additional lower power modes with interrupt driven, wake-up features are available for monitoring motion during periods of inactivity. 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
• Ultra low 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
• Deep embedded FIFO to minimize host processor load
• Autonomous interrupt processing without processor intervention
• Ultra low power event monitoring detects impacts and wakes up fast enough to capture transient event
• Adjustable, low g threshold activity and inactivity detection
• Acceleration sample synchronization via external trigger, SPI digital and I²C interface format
• 16-terminal LGA package, operating temperature range from -40°C to +105°C
