Overview
The ADXL362WBCCZ-RL is an ultralow power, 3-axis MEMS accelerometer produced by Analog Devices Inc. This device is designed for applications requiring high precision and low power consumption. It consumes 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 samples the full bandwidth of the sensor at all data rates, preventing aliasing of input signals.
