i would like to use ad1937 for my design.

design is based on 3 mono line level audio inputs, and 7 mono audio outputs. all ins-outs at 48khz.

I'm looking thou at the reccomended circuits for input outputs that would make the use of this chip extremely expensive.

Could there be an alternative to those input / output circuits?

Is there something i could get rid of (opamps??) without losing too much quality and making the idea viable?
