Figure 27. Left-Channel, Single-Ended Analog Input Mixing Configuration
The TLV320AIC3105 includes the additional ability to route some analog input signals past the integrated data
converters, for mixing with other analog signals and then direct connection to the output drivers. This capability is
useful in a cellphone, for example, when a separate FM radio device provides a stereo analog output signal that
needs to be routed to headphones. The TLV320AIC3105 supports this in a low-power mode by providing a direct
analog path through the device to the output drivers, while all ADCs and DACs can be completely powered down
to save power.

When programmed correctly, the device can pass the LINE2L and LINE2R signals directly to the output stage.
