Hi Dom,

Quote:
-In order to understand this global project, where can i get schematic of it?
send me a PM.

Quote:
-My power amplifier needs 200mV to Pmax and Zinput is 40K : do I need preamplifier or I/V stage is able to drive directly my amplifier?
If you insert a R I/V of 47R you get a max output voltage of ~188mV (TDA1541A full scale current 4mA typical).
So you could try it directly, but i think it would be better with a buffer stage.

Quote:
-I don't see any output filter, that means preamplifier do the job?
My design is as straight as possible and use no output filter to get the maximal sound quality.

Best regards,
Oliver

Got mine too, thx.
Few question, where does the DGND meet the top groundplane ? and is there any specific reason you consider 1541 ground as analogue one ?

Thx
