Vintage Synth Repair

HI

I need to know that type chip is the DAC. That this in CPU board.

I do not have a Synthex to see it.

I see in the schematics, but 7520 do not clarify me much.

If it possible that someone read how is to label on it.

Thanks in advance

Perhaps this is it?

Hi.

Good try, but no it is.

In the schematics the 7520 DAC, the output is the pin 15.
In the AD7520 the pin 15 is Vref input, and the outputs of DAC are pins 1 and 2.

Thanks for the try.
