You need to make your own schematic and place the modeled component into your schematic. The model file I found there on Yahoo might be the LM1875 model - that’s the name of the subcircuit in the file. Perhaps it’s been tweaked to behave more like the TDA2050? You might compare it to the LM1875 model to see if it’s any different.

The .asy file might provide a good symbol for the IC. You can select to apply that .asy to the component you’ve placed into your schematic.

Confused yet?

Oh i got it friend. I did all that. Found some instructions. It was only labeled with TDA2050 because its slightly similar to the LM1875 but far to different to have any practical model comparison. Im fairly certain a spice model doesnt exist anywhere. Would build one myself but i have no idea where to start.

 

Don't you trust the datasheet from the company who designed it but you trust the guesses in a simulation for a different amplifier?

The datasheet for the TDA2050 shows that its minimum supply is 9V or plus and minus 4.5V. A graph shows its fairly low output power using a plus and minus 5V supply and it will work the same when it is biased for a single 10V supply. The supply voltage changes but all the parts values stay the same.

A simulation is simply many guesses and with lots of important spec's missing. I have simulated many amplifiers using little transistors with currents and temperatures much higher than allowed. They simulate fine but blow up in a circuit.

I suppose then i have no practical reason to use spice.

 

By now you are really wasting your time.
Too long of a thread, just for nothing; I am done with it.

Can I delete this thread so it doesn't clutter up the boards?

It should stay up here the next time somebody searches for a TDA2050 LTSpice model. Let them decide if they want to sift through all the chaff to find the nugget pointing them to Yahoo Groups.
