architecture shown in channels 1, 2, 7, and 8. Note that the I2C registers are shown to help the designer
configure the TAS5518C.
Figure 2-2 shows the TAS5518C architecture for fS = 176.4 kHz or fS = 192 kHz. Note that only channels
1, 2, and 8 contain all the features. Channels 3–7 are pass-through except for volume controls.
Figure 2-3 shows TAS5518C detailed channel processing. The output mixer is 8
