The stereo DAC can be fully powered up or down, and in addition, the analog circuitry in each DAC channel can
be powered up or down independently. This provides power savings when only a mono playback stream is
needed.
The TLV320AIC33 includes ten analog audio input pins, which can be configured as up to four fully-differential
pair plus one single-ended pair of audio inputs, or up to six single-ended audio inputs. . These pins connect
through series resistors and switches to the virtual ground terminals of two fully differential opamps (one per
ADC/PGA channel). By selecting to turn on only one set of switches per opamp at a time, the inputs can be
effectively muxed to each ADC PGA channel.
By selecting to turn on multiple sets of switches per opamp at a time, mixing can also be achieved. Mixing of
multiple inputs can easily lead to PGA outputs that exceed the range of the internal opamps, resulting in
saturation and clipping of the mixed output signal. Whenever mixing is being implemented, the user should take
adequate precautions to avoid such a saturation case from occurring. In general, the mixed signal should not
exceed 2 Vpp (single-ended) or 4 Vpp (differential).
In most mixing applications, there is also a general need to adjust the levels of the individual signals being
mixed. For example, if a soft signal and a large signal are to be mixed and played together, the soft signal
generally should be amplified to a level comparable to the large signal before mixing. In order to accommodate
this need, the TLV320AIC33 includes input level control on each of the individual inputs before they are mixed or
muxed into the ADC PGAs, with gain programmable from 0 dB to –12 dB in 1.5 dB steps. Note that this input
level control is not intended to be a volume control, but instead used occasionally for level setting. Soft-stepping
of the input level control settings is implemented in this device, with the speed and functionality following the
settings used by the ADC PGA for soft-stepping.
The TLV320AIC33 supports the ability to mix up to three fully-differential analog inputs into each ADC PGA
channel. Figure 31 shows the mixing configuration for the left channel, which can mix the signals
LINE1LP-LINE1LM, LINE2LP-LINE2LM, and LINE1RP-LINE1RM
