TAS5028A Audio Processing
The TAS5028A digital audio processing is designed such that noise produced by filter operations is
maintained below the smallest signal amplitude of interest, as shown in Figure 1
13. The TAS5028A achieves
this by increasing the precision of the signal representation substantially above the number of bits that are
absolutely necessary to represent the input signal.
