Thanks Dave.

Real DIDO amps have a common mode voltage input. -- Regards, Tony

Except the model and symbol for CD4024 that are needed to run most of the circuits!

This seems to work. G=100MEG seems a bit much. * Ideal Fully Differential OpAmp * /g/LTspice/topic/50198770#msg46663 * .subckt D_OpAmp inp inn outp outn vcm R1 outp n01 1 R2 n01 outn

Correct. Something simple that won't have any convergence issues.

Well, it's very difficult to have 'comprehensive' without 'complex', unless you are prepared to write your own models, or add real-life parameters to existing simpler models.

But you're not looking for a model of a real-life amp, right? I think you said you wanted an ideal model.? That probably means it is lightweight and should simulate fast. Andy

Interestingly, today I am reading "The Chan inductor does not currently directly support Mutual Inductance ( https://ltwiki.org/index.php?title=Mutual_Inductance ) , so unless only a single-winding

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.
