This HSH0815 chip sounds mighty well for a fake. I even tried not connecting pin 4. It is still working. So it must be an "A" chip. Can't it be that Philips produced a new batch in 2008 and this is a genuine chip?

Did you guy's hear of any fake SAA7220P/B chips? The one I received with this "fake" DAC is produced in 2005. See attachement.

Philips became NXP in 2006

As for the 7220, also does not sound right. There are DSG chips from 89, can't imagine the same plant making them in 2005. Maybe it's an A or C version they rebadged. You could verify this i think by looking at the datasheets and then measure. Different powerconsumption, filter characteristics etc between them.

I had one of those R1 DAC's in a Marantz CD50?

aquapiranha · 4th September 2009, 10:14 PM

It was used in many DAC's. Mine is an Arcam Alpha 5 Cd player.

Is it a TDA1541a or a plain TDA1541? If an "a", I'll take it.
