Hello,
I built S/PDIF receiver based ond DIR9001, PCM1794A and LME49725 ics
BUT, when I check output of OP-amps (I/V converters) I get negative DC component at about -4.80V on every for op-amps
and here is with sinosuidal input:
And I made it as it was writen in datasheet, and here is my schematic 
So, I suppose, output current of PCM1794A have positive DC components ?
Output of balanced/unbalanced convertor sounds great, but I notice this negative output because current of negative rail of power supply are 3x larger than on positive rail and thus I get too much heating od power supply heatsinks.
It looks like output of PCM1794A is overbiased, if I get -4.80V it when I convert it from I to V , I get input current at about -6.4mA DC. so I am wondering why DC component exist at output of converter anyway.
The other thing I notices is voltage on VcomL and VcomR which is 2.4V (refered to GND).
Thank you.
