Regarding chips for DMA Sound

Here a couple of questions arose about mikrukh. The subject uses
K572PA1 bourgeois analogues of AD7520. So in the diagram, the digital inputs (or
digital) D0-D9 are located on legs 13 by 4, respectively, but for the bourgeois AD7520 it’s the other way around, i.e. D0-D9 lie on 4 to 13. Who is right here,
could there be an error in the circuit?
Second, the operational amplifiers in the subject - in what housing are they located,
in DIP08 or DIP14? (well, that is, with eight legs or 14?). This is where I'm stuck...

Thank you all in advance for your answers.

Ask the one who drew the circuit, IMHO it’s a mistake.

There are 8 legs, BUT they are NOT DIP, they are round (and yellow)!

You apparently didn’t understand me. I ask in which Packages these
Ouchki are located - with eight legs or with fourteen? And everything else doesn’t
interest me.
Therefore, due to the lack of information, wait for now, but I’ll look further, even though
there is a free and good one at work - a direct connection with the central German
Bone.

All the best

As you turn it on, that’s how it will be located!

AK> What does this mean?

There the DAC is connected either according to a standard circuit, or according to a more different one,
it seems like the signal from the power supply is replaced. So the bits are also reversed
.

Well, how should they be placed now?
D0-D9 go from 4 to 13 legs or vice versa
D0-D9 go from 13 to 4 legs?

I don’t know where D0..D9 is, but it should be correct on the diagram!

Everything is very simple - if the signal from the DAC is taken from the 1st leg, then pin 13 is D0. And if the signal is taken from pin 15, then D0 is the 4th leg of the DAC.
