Inputs can also be selected as single-ended instead of fully-differential, and mixing or muxing into the ADC PGAs
is also possible in this mode. It is not possible, however, for an input pair to be selected as fully-differential for
connection to one ADC PGA and simultaneously selected as single-ended for connection to the other ADC PGA
channel. However, it is possible for an input to be selected or mixed into both left and right channel PGAs, as
long as it has the same configuration for both channels (either both single-ended or both fully-differential).
Figure 32 shows the single-ended mixing configuration for the left channel ADC PGA, which enables mixing of
the signals LINE1LP, LINE2LP, LINE1RP, MIC3L, and MIC3R. The right channel ADC PGA mix is similar,
enabling mixing of the signals LINE1RP, LINE2RP, LINE1LP, MIC3L, and MIC3R.

ANALOG INPUT BYPASS PATH FUNCTIONALITY
The TLV320AIC3106 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 TLV320AIC3106 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.
For fully-differential inputs, the TLV320AIC3106 provides the ability to pass the signals LINE2LP-LINE2LM and
LINE2RP-LINE2RM to the output stage directly. If in single-ended configuration, the device can pass the signal
LINE2LP and LINE2RP to the output stage directly.
