Overview
The ADXL362BCCZ-RL7 is an ultralow power, 3-axis MEMS accelerometer produced by Analog Devices Inc. This device is designed to measure both dynamic acceleration resulting from motion or shock and static acceleration, such as tilt. It features a digital output and operates within a wide supply voltage range of 1.6 V to 3.5 V, making it versatile for various applications. The ADXL362BCCZ-RL7 is particularly notable for its low power consumption, with a standby current as low as 10 nA and a motion-activated wake-up mode consuming only 270 nA at a 6 Hz measurement rate.
