Aaaah, sorry... I was in hurry and read DAC and not ADC.
Original Ferranti ICs not only rare but rather expensive too.
But they produce much better sound quality that the resistance ladder for the same task.
I am sure there are some cheaper China copies too.
So it should be ZN427. I have seen only one piece in my lifetime, my roommate made a digitizer for his A500+, it was in 1994.
It was really small, the whole circuitry fit into the housing of a centronics connector., though he adjusted the signal level externally.
