The ADXL362 is an ultra-low 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 utilize 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.

The ADXL362 is designed for applications requiring minimal power consumption while maintaining high-performance metrics. With its ultra-low power operation, it is particularly suitable for battery-operated devices, such as wearable technology, fitness trackers, and other portable electronics. The device features a 3-axis sensing capability, allowing it to measure acceleration in three-dimensional space, which is crucial for applications involving motion detection and orientation sensing.

One of the key advantages of the ADXL362 is its ability to operate in different modes, including a low-power mode that allows it to function with minimal energy consumption while continuously monitoring motion. The motion-triggered wake-up mode is particularly noteworthy, as it enables the device to enter a deep sleep state to conserve power and only activate when motion is detected. This feature is essential for extending the battery life of devices that rely on the accelerometer for functionality.

The accelerometer samples the full bandwidth of the sensor at all data rates, ensuring that it captures accurate and high-fidelity motion data without the risk of aliasing that can occur with undersampling techniques. This capability makes it suitable for applications requiring precise motion analysis, such as gesture recognition and activity tracking.

In terms of interfacing, the ADXL362 typically communicates via a digital interface, such as I2C or SPI, allowing for easy integration with microcontrollers or other digital processing units. The device also includes built-in features such as programmable thresholds and interrupt capabilities, which can be configured to suit specific application needs.

Overall, the ADXL362 represents a significant advancement in MEMS accelerometer technology, offering a combination of low power consumption, high performance, and versatile application potential, making it a valuable component in modern electronic designs.The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 ?A at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode.
