Working Principle of EVAL-ADXRS453Z-M

The working principle of the EVAL-ADXRS453Z-M is based on the ADxRS453Z dual-axis gyroscope. The gyroscope measures the angular velocity of a body in a given direction. It consists of two sensing elements, one measuring angular velocity in the x-axis and the other in the y-axis. The x-axis sensing elements measure angular velocity in the roll axis, while the y-axis sensing elements measure angular velocity in the pitch axis. The sensing elements are also coupled with temperature compensation electronics to ensure that the measurements are accurate even in changing temperatures.

The integrated signal processing circuitry converts the raw rate and temperature information into linearized real numbers. The board further contains an ADC channel to convert the multi-bit linearized readings into a single single-bit digital signal. The single-bit digital signal is then processed by other devices to achieve a desired output, such as navigation output or robotic motion control.
