Hallo
Ich bin dabei mich in LTSpice einzuarbeiten und will eine kleine Schaltung simulieren. Ich verwende den OP OPA345, der nicht vorhanden ist. Also habe ich mir von TI die Spice Dateien heruntergeladen. In der Zip waren 3 Dateien, OPA345.slb, .sch und .MOD. Laut Anleitung ist für mich nur die .MOD Datei mit dem Spice Code relevant. Ich habe den Beispiel-OP pole1 modifiziert und ich kann das Bauteil in die Schaltung einsetzen. Wenn ich die Schaltung simulieren will, erhalte ich folgenden Fehler: "Too many parameters for subcircuit typ2 "opa345" (instance: xu1)" Woran liegt das?
Anbei mein Symbol und die Spice-Datei von TI
Vielen Dank, Tilo

- This macromodel has been optimized to model the AC, DC, and transient response performance within
- the device data sheet specified limits.
- Correct operation of this macromodel has been verified on MicroSim P-Spice ver. 8.0 and on
- PENZAR Development TopSPICE ver. 6.82d. For help with other analog simulation software,

- FOR MORE ACCURATE VOLTAGES YOU MAY WANT TO USE VNTOL=1E-7 AND / OR RELTOL=0.0001
- MODEL TEMPERATURE RANGE IS -40 C TO +125 C, NOT ALL PARAMETERS ACCURATELY TRACK THOSE OF AN ACTUAL OPA345
