Google turned no datasheets. Someone said I could have anything I wanted from their parts bin, so I chose this, because it looked cool.
pigrew:
It's a DAC (digital to analog converter) made by the PMI company. The part number is DAC-01. It is a 6-bit design, and uses a R-2R ladder circuit.

I found a few books containing datasheets for it:

1986 PMI
1976 PMI

The datasheet even has a photo of the top metal layer (attached).

Thanks!  I guess I came to the right place :-+ Out of all the uses on the datasheet, "telephone system digitizing" definitely sounds the coolest, I didn't know they were already doing that in 76.

So basically it was a 6 bit dac with a sampling rate of 50hz? I wonder what it sounded like... [edit] could something like sigsaly even have bit depth?
