The ADXL362 uses a MEMS (MicroElectroMechanical Systems) accelerometer sensor that outputs the acceleration data along the X, Y, and Z axes. The data can either be transmitted via digital (SPI/I2C) or analog outputs. It is designed for low-power consumption, making it highly suitable for battery-operated devices.
The SPI/I2C interface allows communication with a host microcontroller or other devices, while the analog outputs (XOUT, YOUT, ZOUT) provide raw data for users who require direct analog readings.
