The BIBO models from TI are incredibly complex. They model? lot of parameters. **** * AC PARAMETERS ** * CLOSED-LOOP OUTPUT IMPEDANCE VS. FREQUENCY (Zout vs. Freq.) * CLOSED-LOOP GAIN AND

What I mean is that there are few real-life BIBO opamps,from which SPICE models with real-life features, such as offset and PSRR could be produced. -- This email has been checked for viruses by AVG

Here is the thread I found on fully diff OpAmps /g/LTspice/topic/50198770#msg46663

XSPICE models are minimalistic and designed for speed. Complex models would slow simulations to a crawl. In this case the "XSPICE way" for making a fully differential OpAmp creates a model with

A model that would work for both LTspice and any Spice 3 simulator. The model will also be used in mixed-mode simulations with XSPICE models.

Hello John W. I have uploaded the complete Robertugo/SwitchAna files from my personal archive. It appears to contain all that is needed for the 4051, 52 and 53 parts. I hope this helps.

Yes, because it's quite easy, and probably cheaper, to use 2 or 3 sections of a quad opamp to make a good balanced-in/balanced-out circuit. -- This email has been checked for viruses by AVG antivirus

Tom, Maybe you did not understand my question. Are you looking for a model to run in LTspice, or are you looking for a model to run in XSPICE (or other SPICE programs)? The ideal op-amp models that

The generic Spice model would be usable in LTspice or Spice programs that support XSPICE. I found 2 on this forum from 2011 using various search terms. There are many choices for an generic OpAmp with

I am a little confused about the request.? Does that mean you want a model that will be used in XSPICE?? Or one for LTspice that behaves similarly to a model you already have for XSPICE? If it is

Looking for ideal fully differential amplifier spice model for XSPICE simulations. The one I have based on the XSPICE "gain" code model doesn't have any CMRR or care if outputs are swapped. Anything

Andy, I had to do a deeper search in my archive, but found them. I uploaded a newer zip file with the missing asy files. Mike

Story of my life! That's why I usually use 'JMW' rather than 'JW', but at one time there were at least three people called John Michael Woodgate (only very distantly related, if at all) in Britain. --

Sorry!? That was the other John W (Waugaman). Andy ( #DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2 )

I can live without them, and I'm sure Andy will provide all the help you need. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

Thanks, Mike. I don't know if it matters (to John W), but your uploaded .zip file is missing the symbols "1To2.asy" and "switchana.asy". Andy

John & Andy, I found the files in my offline LTspice storage location. Files are uploaded as 4053_tercio.zip. I have no idea if the files are current with the latest Bordodynov library. You will

A much older version of "SwitchAna.Lib" was also mentioned in this 2008 message thread: /g/LTspice/topic/50176653 ("X046 Lib & Cmos Switchs Libs") but it appears they did not

It's difficult to trace back in time, 7 years later.? But the library file "SwitchAna.Lib" was uploaded and mentioned in this thread: /g/LTspice/topic/50239806 ("Question about

The analog switch library "SwitchAna.Lib" makes reference to various symbols (e.g.? "4053_tercio.asy") and phrases like "The model needs two params: Vcc & Vel see the circuit example..".? Where
