Make outputs single ended on CS4234

Question

I am working with the CS4234 codec for a project It has 4 ADCs and 5DACs. One thing that is confusing me is that the pins are labled AOUT1- and AOUT1+ in the similar fashion for all ADCs and DACs.

The device states it can do single ended, which I believe is what I need to achieve stereo sound. How can I change these various ADCs and DACs to Left and Right input/output channels?

Could I just use the positive for left and then the negative for right? Like are they already in this configuration or do I need to use an op-amp to convert the signals?

No. Single ended would just be using AOUT1+ and ignoring AOUT1-, or combining both + and - into a single signal with an op-amp. For stereo you would use AOUT1 and AOUT2 in either single-ended or differential mode.

Using an op-amp to make a differential output into single ended can be done like this:
