Overview
The ADXL362BCCZ-MI-RL7 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, making it ideal for mobile and IoT devices. 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 ADXL362BCCZ-MI-RL7 samples the full bandwidth of the sensor at all data rates, ensuring no aliasing of input signals.
