TAS5504 DAP Architecture
1.4.1 TAS5504 DAP Architecture Diagrams
Figure 12 shows the TAS5504 DAP architecture for Fs = 96 kHz. Note the TAS5504 bass management
architecture shown in channels 1, 2, 3, and 4. Note that the I2C registers are shown to help the designer
configure the TAS5504.
Figure 13 shows the TAS5504 architecture for Fs = 176.4 kHz or Fs = 192 kHz. Note that only channels 1,
2, and 4 contain all the features. Channel 3 is pass-through except for master volume control.
Figure 14 shows TAS5504 detailed channel processing. The output mixer is 4X2 for channels 12 and 4X3
for channels 3 and 4.
