GENERAL DESCRIPTION
The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 µA at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates.

FEATURES
    Ultralow power
        Power can be derived from coin cell battery
        1.8 µA at 100 Hz ODR, 2.0 V supply
        3.0 µA at 400 Hz ODR, 2.0 V supply
        270 nA motion activated wake-up mode
        10 nA standby current
    High resolution: 1 mg/LSB
    Built-in features for system-level power savings:
        Adjustable threshold sleep/wake modes for motion activation
        Autonomous interrupt processing, without need for microcontroller intervention, to allow the rest of the system to be turned off completely
        Deep embedded FIFO minimizes host processor load
        Awake state output enables implementation of standalone, motion activated switch
    Low noise down to 175 µg/√Hz
    Wide supply and I/O voltage ranges: 1.6 V to 3.5 V Operates off 1.8 V to 3.3 V rails
    Acceleration sample synchronization via external trigger
    On-chip temperature sensor
    SPI digital interface
    Measurement ranges selectable via SPI command
    Small and thin 3 mm × 3.25 mm × 1.06 mm package
