LM358 #103

Hello. This is more like a hint, not an issue so I write it in an open form.

Your file stmbl/hw/spice/LM358.lib was quite helpful for my Eagle simulations, however it contains a model of just one OpAmp and LM358 is a dual op amp IC. You can change it by adding the following lines in the beginning:

.SUBCKT LM358_DUAL       IN1+ IN1- OUT1 IN2+ IN2- OUT2 V+ V-
X_OPAMP1 IN1+ IN1- V+ V- OUT1 LM358
X_OPAMP2 IN2+ IN2- V+ V- OUT2 LM358
.ENDS

And use than LM358_DUAL in your Eagle. I do not know if you are really using a dual OpAmp, but I believe that this information can be useful anyway.

Thanks for the info. We use this lib only for the ltspice simulation of the feedback interface (wich uses only a single opamp).
