7.3.4.1 DAC Processing Blocks — Overview

The TLV320DAC3203 implements signal processing capabilities and interpolation filtering via processing blocks. These fixed processing blocks give users the choice of how much and what type of signal processing they may use and which interpolation filter is applied.

Table 3 gives an overview over all available processing blocks of the DAC channel and their properties.

The signal processing blocks available are:

  • First-order IIR
  • Scalable number of biquad filters
  • 3D – Effect
  • Beep Generator

The processing blocks are tuned for typical cases and can achieve high image rejection or low group delay in combination with various signal processing effects such as audio effects and frequency shaping. The available first-order IIR and biquad filters have fully user-programmable coefficients. The Resource Class Column (RC) gives an approximate indication of power consumption.
