I don't know necessarily what I'm doing here.
So Here is where I'm at:
I'm trying to work with the TI TPA3126D2 Datasheet is here:
http://www.ti.com/lit/ds/symlink/tp...l-wwe&DCM=yes&ref_url=https://www.mouser.com/

Trying to setup a spice model for this in LTspice
TI has the .lib .tld & .tsm files for download on the site. The .lib is attached below
I've looked up online how LTspice says to do this. Apparently I need a .sub file or .SUBCKT file.
Now I don't know exactly what those files do, I get the feeling that they are net list descriptions that allow LTspice to build a component drawing from, but I fully expect I'm wrong with that.

Ok I'm rambling, The ultimate question is can I build a new component drawing and then assign the .lib file to it to utilize it in spice sims in LTspice?

 

Okay I think I'm a little closer now.
I have the .lib in ltspice
Here it is copied.

Set up my spice directive: .include C:\Program Files\LTC\LTspiceXVII\lib\sub\TPA3116D2.LIB

And now I get this error:
Port{pin} count mismatch between the definition of subcircuit 'tpa3116d2' and instance 'xu2'.
The instance has more connection terminals than the definition.

Now I get that it is saying that I have more pins on the component I drew up (The actual component has 32 pins so that's what I drew up)
I'm just wondering when I redraw this component what order do I draw the pins? Meaning does should the netlist pin out be in the order that the pin shows up in the list, or the way it is actually laid out on the circuit? And what about all of those pins that are after the "+" (IE: + MUTE OUTNL OUTNR OUTPL OUTPR PLIMIT PVCC SDZ) I know most of these pins are the outputs of the circuit except for mute plmit pvcc and sdz. But even those are used as well.
I'll keep working at it on my end.
Any one who decides to help, thank you.

 

You see abracadabra in the text file. This means that it is encrypted for ORCAD. And this is very bad news for you - it is not suitable for LTspice. TI encrypts its models. True, he recently began to "correct" and in addition to encrypted models, he also supplies unencrypted models. Search the site. Maybe you are lucky. Good luck!
