Hi everyone,
I am dealing with an electronic circuit. It has a small non-inverting and inverting circuit inside. They had opamps but ltspice cannot recognize its own opamp. It gives me error : "Unknown subcircuit called in: xic7 n001 n009 n008 n010 n004 p001 ltc6268-10 " . I uninstalled the LTspice from my computer and installed again but there is no change. Indeed, If I draw another basic circuit with this opamp It works. If you have an idea please help me.

Where did you get the LTC6268-10 model from? It's not in the opamps folder that LTC installs.
Is the model intended for a different spice? It includes uplim and dnlim functions which I've not come across before.
I got it from LTC/lib/sub direction inside the LTC6.lib folder. This opamp is one of the opamps which LTspice includes. But I had same problem a few days ago for an ordinary LTC opamp -OPA07- . I thought that If I reinstall LTspice It might improve but it is not.

1. Removed and re-added LTC6268-10, U1, component using the component selector.
Probably didn't have to do this but left it that way.
2. Removed the LTC6268-10 .subckt statement from the schematic. It wasn't needed.
3. The diode was defined twice with two .subckt statements on the schematic.
I commented out the first line like this:
*.subckt D 1 2
4. Assigned "PMLL4448" to the value field of each diode.
I have same problem again with another circuit. "unknown subcircuit" why is it happening? I couln't figure out! Now I am trying an basic opamp differentiator amplifier circiut. I try to understand behaviour of an opamp but i could not make it. It tells unkonwn subcircuit for opamp. Could you please tell me how will I deal with this unknown subcircuit problem? .lib file is in ltc library and also in the same folder with .asc file.
thank you for your help. my major is not electronic but i try to learn so i am sorry i could not recognize it. now i learn what is a webbench. thank you again.
