Re: Whither 4053_tercio.asy
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.

Re: Looking for ideal fully differential amplifier spice model
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

Re: Looking for ideal fully differential amplifier spice model
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

Re: Looking for ideal fully differential amplifier spice model
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

Re: Looking for ideal fully differential amplifier spice model
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
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

Re: Whither 4053_tercio.asy
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. --

Re: Whither 4053_tercio.asy
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

Re: Whither 4053_tercio.asy
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

Whither 4053_tercio.asy
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

Re: OPA891 / OPA2891 Model Needed
Just to be clear - Adding "OPA891" as the Value2 attribute has nothing to do with putting your symbols and models in your user-defined locations. Andy

It will nearly do that if you create your own libraries for symbols and models. See 'Settings > Search paths' in the Help. You do have to select the folder from a drop-down list. -- This email has
