Lately I've started designing an audio amplifier with usb input. After searching I found about T.I. and their usb audio interface-codecs.
I am going to talk specifically about the PCM2900C, even thought all of them seem to have a similar dac.
In the datasheet it is stated that the output voltage of this dac is 0.6*Vcccl Vpp with 0.5*Vcccl V center voltage. So how these values affect the outputted ac signal? For example if I were to use 3.3V for Vcccl, then with respect to AGNDC what will the Vout voltage be:
If the connected computer is not outputting any audio.
The min and max voltages when the computer is outputting audio.
Also I am wondering how and if these voltages are affected if I were to add coupling capacitors in series with the Vout pin and the load/speaker/amp.
(I am reffering to the "typical circuit connection" design as demonstrated in the datasheet of the PCM2900C)
