5.6.7
Digital Mixing and Routing
The TLV320AIC3120 has four digital mixing blocks. Each mixer can provide either mixing or multiplexing
of the digital audio data. The first mixer/multiplexer can be used to select input data for the mono DAC
from left channel, right channel, or a mix of the left and right channels [(L + R) / 2] . This digital routing can
be configured by writing to page 0 / register 63, bits D5–D4 for the DAC mono channel.
5.6.8
Analog Audio Routing
The TLV320AIC3120 has the capability to route the DAC output to either the headphone or the speaker
output. If desirable, both output drivers can be operated at the same time while playing at different volume
levels. The TLV320AIC3120 provides various digital routing capabilities, allowing digital mixing or even
channel swapping in the digital domain. All analog outputs other than the selected ones can be powered
down for optimal power consumption.
