[sdiy] Using a Burr-Brown PCM53JP-V DAV in a CV voltage quantizer

[anthony]

I've seen a lot a few cool ideas using 12-bit parallel input DAC's to create 
a stairstep output to be used with other circuitry to make a control voltage 
quantizer. The DAC I've seen used most is the AD7524 (or something like 
that).

I have a Burr-Brown PCM53JP-V that I got from a dead Technics CD player made 
in 1985. I was wondering if anyone had messed about with one of these 
DAC's - that is the DAC designed for audio. The PCM53 (and PCM54 I'd wager) 
could be good candidates because they have parallel inputs. I'd imagine the 
only reason that'd keep anyone from experimenting with one of these DAC's is 
because it's because it's expensive. You just have to go scavanging old old 
CD players like I do.

The one I have is a voltage output type, which is I guess what you'd want. 
If I had a spare PCM54, I'd have a choice of current or voltage out, but the 
one PCM54 I do have is currently in it's intended place in my Digitech 
GSP-5.

Scott Stites has done some very interesting work on the use of DAC's in 
quantizers.

So the question is, has anyone experimented with one of these bad boys?

PS - I just got two Burr-Brown PCM61's from a dead Denon. They don't look 
like parralel inputs. 'Specially since the front said "20-bit 8-times 
oversampling blah blah..." I haven't takent the time to chase down a 
adatasheet...
