  Step 1:  Analog Design

Open a Report
The analog stage of a digital converter is one of the more important design aspects. For instance, Self-Noise will reduce the resolution of an A/D converter due to the fact that for every 3db of Self-Noise, the signal loses 1 bit of resolution causing the low-level audio to be lost in the noise.
  Step 2:  Clock Design

As discussed earlier, the accuracy of the clock is vital in reducing Jitter. This is the case whether the clock is running internally or being locked to an external source.
  Step 3:  Power Supply

It is extremely important that the digital and analog parts of the converter receive the highest-quality, most stable, interference free power supply.
  Step 4:  Digital Design

Digital signals operate like radio broadcasts. Consequently, these signals can leak into other circuits in the converter creating noise and degrading the performance. Digital circuitry and boards need to be laid out carefully so the right relationship is established between analog and digital.
