Especially Crutschow probably may help me at glance now. Last time I imported sth in LT-Spice was more than year ago thus I completely forgot how to. So, I got a modell from Ti.com the LMV721.ckt. Then I pushed that into C/Programs... /LTSpice4/lib/sub under name LMV721.ckt. and restarted Spice.
At last I draw the schematics using the "custom opamp" for what right mouse and clear off all descriptors, thus the instance name =Op1 (Actually I have a complete opamp cemetery there, all dosen are identical and differs only with Op1, Op2, Op3....); Value =LMV722, Value2 =empty, Spice line =tried as empty as LMV722, Spice line2 =empty. At right on desktop .op icon and wrote .lib LMV722.ckt and put on the circuit corner.
When I ask to Run, those small black man icon in shade said [Could not open library file "LMV722.ckt"] and looked on me with despair
So.... Where I hide my deadly mistake??
Thanks in advance for help.
