Overview
The ADXL362BCCZ-MI-RL, produced by Analog Devices Inc., is an ultralow power, 3-axis MEMS accelerometer. This device is designed to consume minimal power, using less than 2 µA at a 100 Hz output data rate and as low as 270 nA in motion triggered wake-up mode. Unlike other accelerometers that use power duty cycling, the ADXL362 does not alias input signals by undersampling, ensuring it samples the full bandwidth of the sensor at all data rates. The accelerometer provides 12-bit output resolution, with an option for 8-bit formatted data for more efficient single-byte transfers when a lower resolution is sufficient.
