I have no information on that.

Considering that the DOC is based on ICS, Inc.'s mixed-signal ASIC 
technology, I would think that Ensoniq went with something from the ICS 
design library.

Unfortunately, the oldest ICS databooks I found are from 1994. So I'm 
not sure how closely they reflect the situation more than 10 years 
earlier when the DOC chip was designed and manufactured.
