LTSpice

[Michael Robinson]

I need to simulate a circuit with an lm393 comparator in it. I went to th
yahoo group and got a file called lm393_st.txt. I renamed it lm393.sub an
put it in the sub folder. Then I drew my circuit using a universal op am
symbol, which I named lm393. LTSpice doesn't recognize it, with or withou
an include statement. What do I do?

Hello Michael,

The examples in the LTspice Yahoo group run out of the box.
Just unzip the zip-file from Files>Lib to any folder and start the .asc
file.

Files > Lib > LM339_LM393.zip
http://tech.groups.yahoo.com/group/LTspice/files/%20Lib/

Best regards,
Helmut

Hello Michael,

The examples in the LTspice Yahoo group run out of the box.
Just unzip the zip-file from Files>Lib to any folder and start the .asc
file.

Files > Lib > LM339_LM393.zip
http://tech.groups.yahoo.com/group/LTspice/files/%20Lib/

In the library where it says "Comparator LM339 and LM393 Three models for
this comparator" I click on "Comparator LM339 and LM393" and it takes me to
this link

http://tech.groups.yahoo.com/group/LTspice/files/%20Lib/Comparator%20LM339%20and%20LM393/

that has various .txt, .asc and .asy files.

I want to use the lm393. I have three choices:

lm393_st.txt, LM393A.5_1_ti.txt, or LM393_ST_TI_AI_test.asc.

As I explained in my previous post, I got nowhere with the text files. So
this time I try opening LM393_ST_TI_AI_test.asc in LTSpice.

A schematic opens, but without the symbols for the comparators.

I go back to the collection of comparator files so I can retrieve the symbol
LTSpice is calling for.

I find XOPAMP_ST.ASY and save it in the opamp folder in the symbol folder in
LTSpice.

It turns out the file linked to from "XOPAMP_ST.ASY" on that page was
actually named XOPAMP_ST-2, so I rename it XOPAMP_ST and now when I open the
test schematic, I get a symbol in the ST portion of the test circuit.

I want to see if it works, so I delete the other test circuits and click
simulate.

I get the message, "Could not open include file 'lm393_st.txt'"

Maybe you can explain what my next step should be.

Hello Michael,

I have send you an email with an attached example.
