Figure 31. Left Channel Fully-Differential Analog Input Mixing Configuration
Three fully-differential analog inputs can similarly be mixed into the right ADC PGA as well, consisting of
LINE1RP-LINE1RM, LINE2RP-LINE2RM, and LINE1LP-LINE1LM. Note that it is not necessary to mix all three
fully-differential signals if this is not desired – unnecessary inputs can simply be muted using the input level
control registers.
