Hi everyone, and thanks for the help.
Im trying to check on LTSpice the function of two components in the same configuration: lm741, lm339.
I thought that there would be a diffrence but I encountered a simulation problem regarding the lm339.
first of all the circuit with the 741:
The code of 741 is attached as the 339 code.
and I saw as i expected:
The green graph is for the AC source just for checking.
now I changed the component to the 339:
But now the simulation seem to be stuck/ working very slow (guessing because somthing is wrong):
after a long time I'll eventually get the "normal" graph as in the 741 but then the Vout will be different and not the way I calculated it to be:
why does this happen? I checked the parameters that a 339 can get as inputs and it seem to be fine? what is the difference from the 741 that causes the problem?
Big Thanks, Hadar.
