In this paper, the features of high speed digital-to-analog converter ADS803, pins and working way are introduced, and the interface design with digital signal processor TMS320LF2407 is given.

DSP in the analog signal is converted into digital signal processing real-time after high-speed dedicated processor, its processing speed than the fastest CPU faster 10 to 50 times.

These simulations, however, led to digital processor code that simulated or performed nearly the same task on samples of the signals that the analog systems did on the signal.
