Could someone please provide me with the symbol files required to load an .asc with an LM324 symbol in it.

I only get "Couldn't find symbol(s): LM324" if I open DualRamp.asc

PLEASE

I checked on the internet, could only find a LM324.txt that I don't know how to load

 

Replace it with a generic opamp.

Notice the "(or other op-amp)" in the asc file

 

Or you could follow the instructions on this page, which I'm pretty sure you got the LM324.txt file from. If not the instructions are just below fig.4.

the "other op-amp" in the asc file is a label, if I load a generic op-amp into the right place in the schematic it says: "Unknown subcircuit in: xu1 n004 n002 n001 0 out opamp2" when running it

 

Here you go

 

@Alec_t are you sure you didn't miss a file? following the instructions give me "Unknown subcircuit in: xu1 n004 n002 n001 0 out opamp2" or something similar, and loading your file pasted into either folders still give me "unknown symbol" error... the examples run though

 

got it, had to .include thanks

 

Here you go.

Just copy LM324.ASY into ..\LTC\LTspiceIV\lib\sym\Opamps
and copy LM324.MOD into ..\LTC\LTspiceIV\lib\sub

 

solved thx
