I want to add buffer stages to the output of this chip so that I have both unbalanced and balanced mono outputs. These can be active at the same time, but I see three ways of doing this:
1. Use one line out and create a unbalanced to balanced circuit.
2. Use both line outs and create a balanced to unbalanced circuit.
3. Use one line out for unbalanced out and the Headphone outs for balanced. Not sure if this is do-able, but it would give me the most flexibility. Can I just connect a high impedance input to these?
This is a single supply design.
