Looking for info, comments, or even schematics (topologies) on generating a clean Vref -- via a dedicated opamp --for TDA1543 and TDA1545 (and preferably the latter).
Informally, I've heard (read) some DIYers mention this strategy, but I'm not sure if it has been formally discussed in a forum, at least via my non-exhaustive archive searches -- please correct me if I'm wrong!
Thx

Have you seen the 'Lossless SD Player' thread? It uses a led-referenced shunt reg though, not an op-amp.
