LEFT AND RIGHT OUTPUT CHANNEL MIXERS
Figure 25 Left/Right Output Channel Mixers
The left and right output channel mixers are shown in Figure 25. These mixers allow the AUX inputs,
the ADC bypass and the DAC left and right channels to be combined as desired. This allows a mono
mix of the DAC channels to be performed as well as mixing in external line-in from the AUX or
speech from the input bypass path.
The AUX and bypass inputs have individual volume control from -15dB to +6dB and the DAC volume
can be adjusted in the digital domain if required. The output of these mixers is connected to both the
headphone (LOUT1 and ROUT1) and class D headphone (LOUT2 and ROUT2) and can optionally
be connected to the OUT3 and OUT4 mixers.
