I forgot to mention - I also uploaded "Pease MFB BP filter with UnivOpAmp2.zip" to the Temp folder.? It substitutes the UniversalOpAmp2 in place of the LM4562, and it moves the "OUT" node to the

That actually does work too, except for these two things: * You must remember to also add a ".lib" command to the schematic to load the necessary library file. * The actual subcircuit names of the

That's what I have now done, but I had strange difficulty in getting rid of the .ASC with the wrong OUT flag.

I agree, a fixed schematic is best.? It would be even better if John had moved the "OUT" node name to the right place.? Oh well. But it really was trivial to delete the ".inc" command and the op-amp

I've updated to include the 4562 model file. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

I was suggesting that,as in this case a device include is missing (happens often), if I could comment out the ".inc LM4562_NS.sub", and supposing I had many opamps that use that model, It would be

Well, you would have already known that it was not possible to simply do that because you already had to point to the LM4562_NS.sub (or whatever) model file. The universalopamp is no different to any

Hi John,? I was really only intereseted in advising that your Pease zip was missing the LM4562_NS.sub ifile needed for simulation of the actual circuit you posted. The UniversalOpAmp thing was just

I made a ZIP with UniversalOpamp, but Tony seems to have made it superfluous.? I will upload it, if it still has value. -- This email has been checked for viruses by AVG antivirus software.

LOL! Not the same as 'simply change the name'.? T

Actually, you can already do exactly that. 1. Place opamp2 symbol (if not already present) 2. Change the Value to level2 3. Add: .lib universalopamp2.lib as a SPICE directive You're done! Of course,

Hi John, Could you update your zip of the circuit to .inc LM4562_NS.sub?Btw, it occurs to me because of this that a nice feature for LTspice would be to be able to simply change the opamp name on the

I can not change the answer been sent. noticed.

if? 0< {AMP}*V(D1)<10, G2 output {AMP}*V(D1), based on your params, this part is 10 times "higher" of amplitude value of the "source" D1. I assume you did not divide 10 (AMP) when you probe the G2.

I did not notice if someone has already find the same as "reason". you should probe the G2/10. about the equation, V=limit({AMP}*V(D1), 0, 10) if? {AMP}*V(D1)<10, if output {AMP}*V(D1), based on your

Hi Ben, You can always create your own symbol as a .asy file with the same name as the subckt. Here's the spice directive that I add to my schematic anytime I need a pot. Just make sure the .asy file

There are many (MANY!) 3-pin potentiometer symbols and models that you can find, if you really desperately need one.? I almost never use a potentiometer symbol+model, because you don't need one.? A

The library you want (probably) is: potentiometer_standard.lib </g/LTspice/files/z_yahoo/Tut/Potentiometer/potentiometer_standard.lib>. Note: this only contains the models, not any

HI, Ben. Search in the group archives, the folders in Files which have 'z_,,,' names. You will find more than one model. for 'potentiometer'.? That emwonder site no longer exists. -- This email has

Hi, my name is Ben and I was looking for the 3pin POT model in your database. I found this link: http://www.emwonder.com/spicemodels/. But I cannot open it. Can anyone help me? thank you already. -Ben
