hello everyone

Can anyone tell me how to add OP amp 741 to LT spice simulation tool

 

For LTspice IV:
Put the .lib file in C:\Program Files (x86)\LTC\LTspiceIV\lib\sub.
Put the .asy file in C:\Program Files (x86)\LTC\LTspiceIV\lib\sym\Opamps

 

Thank you very much for reply

 

Fafor LTspice IV:
Put the .lib file in C:\Program Files (x86)\LTC\LTspiceIV\lib\sub.
Put the .asy file in C:\Program Files (x86)\LTC\LTspiceIV\lib\sym\Opamps

after downloading and adding to that folder what should i do i couldnot see the LM741 in that opamp folder of LT SPICE Directive

 

Did you close and reopen LTspice?
It should be there if you put the .asy file in the sym\Opamps folder.

 

Are you using LTS version IV or XVII? Version XVII reads its data from the ....../Documents/LTspice/lib path when using Windows10.

yes i am using windows 10 and LTSPICE XVII

 

Then put your .lib file in the Users/....../Documents/LTspice XVII/lib/sub folder and put the .asy file in the Users/....../Documents/LTspice XVII/lib/sym/opamps folder.

 

Then put your .lib file in the Users/....../Documents/LTspice XVII/lib/sub folder and put the .asy file in the Users/....../Documents/LTspice XVII/lib/sym/opamps folder.

Thank you i will update you

 

Hi sir i copied the .lib, .asy files according how you said even though i am not able to see the component in opamp folder

 

If you copied the file correctly and scroll through the C:\Users\User\Documents\LTspiceXVII\lib\sym\opamps\ folder you should see it.

Remove the quotes characters surrounding the .lib command on the schematic.

Hi

Change the statement to:

.lib LM741.lib

 

Hi

Change the statement to:

.lib LM741.lib

i am getting error like can not be open 741.lib even i change to .lib LM741.lib

 

In post #12 you show the wrong path for the file that LTspiceXVII uses.

This is where the file needs to be :-

 

Hi
Post #17 is the correct default path for the .asy symbol file.

The correct default path for the .lib file is:
This PC->Documents->Program Files->LTC->LTspiceXVII->lib->sub

The statement shown in post #15 is correct for the default .lib file path.

 

In Win10, LTspiceXVII installs the .asy files and the sub files in default (or user-specified) locations, but (as far as I can tell) only reads from shadow copies in folders in the Documents path.
