The subject is a MIC preamp with diffential output (PGA2500(Ti)).
If there is a balanced input signal to the FV1, can I do the unbalanced signal inside of the FV1?
AinL=(A/2+COM), AinR=(-A/2+COM)
The COM signal is the picked up noise (No DC, BW limited).
Can I expect: AinL-AinR=(A/2+COM)-(-A/2+COM)=A?
How large is the remaining error?
Thanks!

I don't see why not. The math is 24-bit so any error should be well below your noise floor.
