TAS5518 DAP Architecture
1.5.1 TAS5518 DAP Architecture Diagrams
Figure 14 shows the TAS5518 DAP architecture for Fs = 96 kHz. Note the TAS5518 bass management
architecture shown in channels 1, 2, 7, and 8. Note that the I2C registers are shown to help the designer
configure the TAS5518.
Figure 15 shows the TAS5518 architecture for Fs = 176.4 kHz or Fs = 192 kHz. Note that only channels 1,
2, and 8 contain all the features. Channels 37 are pass-through except for master volume control.
Figure 16 shows TAS5518 detailed channel processing. The output mixer is 8X2 for channels 16 and *X3
for channels 7 and 8.
