I would like some assistance with an AD design for the balanced outputs from the AD1937 codecs. The reference designs I have seen, and on our evaluation board, are typically for unbalanced audio outputs with OpAmps. We need all outputs to be balanced audio outputs. Ideally achieving +18 dBu at 0 dBFS within the codec. i.e., trying to set the maximum output voltage to +18 dBU (~6.15 Vrms), for connection to external audio devices.
Can you please provide me with your recommended parts/schematic to achieve this?
