High-precision data acquisition system of gyroscope based on ADS1255

ADS1255 is low-power-dissipation,high-resolution, 24-bit, and Δ-Σ analog-to-digital converter, provided by TI, which integrate input multiplexer, input buffer, programmable gain amplifier and programmable digital filter. Gyroscope, also known as Angular rate sensor, is a detector of angular movement, using that the High-speed rotary´s moment of momentum is rthogonal to the axis of rotation. It turns rotational speed to Linear analog voltage. This system measure the analog voltage by ADS1255, get the result of angle after integral operation.
