Okay, that's fine, but then, when I have to design and build it all, how will I connect the missing pins?
And then, will it work properly?
These are my doubts.
Who is the design engineer?? If that is you, then you must be the master of your design.? You need to take full responsibility for understanding what the circuit does and how every part of it works.

If you seriously don't know what to do with the extra two pins because you couldn't include them in your LTspice simulation, then it is your job to understand how those two pins work, and how they should be connected, and whether they can be ignored by not connecting to them.? Chances are they can't be ignored, and probably should be connected to something.

When I compared the datasheet with the LTspice symbol, the only two pins I could not match up with the symbol were:
- Pin 8 = Vref
- Pin 15 = SYNC

Now here is where your engineering skills become important.? What do those two pins do?? What does the datasheet say about them?? In one figure in the datasheet it shows one pin connected to ground, and the other pin connected to a bypass capacitor.? But it is your job to read the datasheet and understand what is the right thing to do with those two pins.

Most datasheets from Analog Devices have fairly detailed about what every pin does, and how to use it.? Read the datasheet to find out.

Did you have questions about the naming differences with any of the other pins?
