9.3.4 DAC

The TLV320AIC3204 includes a stereo audio DAC supporting data rates from 8kHz to 192kHz. Each channel of the stereo audio DAC consists of a signal-processing engine with fixed processing blocks, a digital interpolation filter, multi-bit digital delta-sigma modulator, and an analog reconstruction filter. The DAC is designed to provide enhanced performance at low sampling rates through increased oversampling and image filtering, thereby keeping quantization noise generated within the delta-sigma modulator and signal images strongly suppressed within the audio band to beyond 20kHz. To handle multiple input rates and optimize power dissipation and performance, the TLV320AIC3204 allows the system designer to program the oversampling rates over a wide range from 1 to 1024. The system designer can choose higher oversampling ratios for lower input data rates and lower oversampling ratios for higher input data rates.

The TLV320AIC3204 DAC channel includes a built-in digital interpolation filter to generate oversampled data for the sigma-delta modulator. The interpolation filter can be chosen from three different types depending on required frequency response, group delay and sampling rate.

The DAC path of the TLV320AIC3204 features many options for signal conditioning and signal routing:

  • 2 headphone amplifiers
    • Usable in single-ended or differential mode
    • Analog volume setting with a range of -6 to +29dB
    • Class-D mode
  • 2 line-out amplifiers
    • Usable in single-ended or differential mode
    • Analog volume setting with a range of -6 to +29dB
  • Digital volume control with a range of -63.5 to +24dB
  • Mute function
  • Dynamic range compression (DRC)

In addition to the standard set of DAC features the TLV320AIC3204 also offers the following special features:

  • Built in sine wave generation (beep generator)
  • Digital auto mute
  • Adaptive filter mode
