Se vuoi dare un'occhiata, ho caricato un file immagine nella sezione foto. Ok, va bene, ma poi, quando dovrò progettare e costruire il tutto, come collegherò i pin mancanti? E ??poi, funzionerà

I have not looked at yet - but it is very common for SPICE models to have fewer pins than actual pins.? Also, pin names often vary. Andy

You may get help here, but you should report your problem the ADI's Engineer Zone, because the different pin numbers is clearly ADI's problem. -- This email has been checked for viruses by AVG

Hi, I am designing a Step-up Booster based on LT1680, for some reasons: 1)Suitable for high power; 2)Through hole package; 3)Simple external architecture. However, there is a discrepancy between the

1. Which temporary file(s) do we need to keep, if we want to return to a model and execute one of several .meas scripts? 2. Is there a way (maybe in batch mode?) to execute a meas script without

No, that was my oops. That was a quick test to see whether that revealed any unexpected behaviour. I hadn't intended to upload that version. 1 ohm is also the output impedance of the built-in opamp

Regarding what I thought was the lack of rail-to-rail output drive: I missed what was happening in your test circuit.? I missed the fact that your negative supply voltage V- was at 0V.? Oops. And

My (very) limited measurements suggest that the B-source is about 5-10% slower than an A-source, but that might vary considerably with processor and circuit complexity (I only tried on my Ryzen 9

Oops, maybe you missed that one.? An easy oversight. [Edited because this was my mistake.] I am inclined to agree with that.? But I will note that there are some LTspice users who feel its

Quite interesting. Me, I tended to use one of LTspice's built-in Digital devices (diffschmitt, etc.) when needing a generic comparator, but they have disadvantages.? Yours is simpler and in many ways

Very helpful. It would be good to add a .ZIP of all the files to the folder.

All LTspice users should be familiar with UniversalOpamps. There are 7 different UniversalOpAmp models of increasing complexity capable of modelling almost any proprietary opamp to reasonable levels

Hi Andy Thank you so much for your help! I've used the "UniversalOpAmp2" and It's working now. Thanks for your other advices too.

I already mentioned that, but I guess it didn't get noticed. -- Regards, Tony

Tim, If? you want a hint about why your schematic doesn't work, I strongly recommend reading in LTspice's Help about the ".inc" and ".lib" commands. (LTspice? > Dot Commands > .INCLUDE -- Include

I have renamed your file to "Pease MFB BP filter (Tim Hutcheson).zip". The other name ("Pease MFB BP filter (2).zip") was a rather bad choice for a file that would coexist with John Woodgate's

Why would you go to all that trouble?? Just do this: * Delete the old LM4562 symbol * Add a UniversalOpAmp* symbol where the other one was * Optionally, delete the old ".lib LM4562_NS.sub" command It

All, I replaced my "Pease MFB BP filter (2).zip" so that it includes the missing UniversalOpAmp1.lib file and created this topic to track it. Tim *[Moderator's note: The filename has been changed to

Here's another suggestion, if I may add one. When using numbers such as ".008", don't write them that way.? Writing a number with a leading decimal point can lead to mistakes when someone else looks

I wrote: I'm somewhat incorrect, in my explanation.? It is not the finite slew-rate that limits their output voltages.? It is the finite open-loop voltage gain, which defaults to Aol=100K.? They
