Good Morning,
Where can I get a model for TINA-TI of a 4066 or equivalent and/or a model of the OPA211-HT that I can run in LTSpice?
Thanks

Steve,
I am a modelling engineer in Analog eLab.
Does your reference to a 4066 mean the CD4066? If so, it seems we do not have a model for that device.
We have no dedicated LTspice model for the OPA211. Do you need the model immediately, or do we have some time?
The reason I ask is that it is possible (sometimes) for us to tweak a Pspice netlist to run in LTspice.
The resulting model will simulate, but we can't ensure its accuracy since LTspice is not one of our normal platforms.
Regards,

John,
I did mean the CD4066 or any quad switch you might have. I found A Pspice model of a 4016 and successfully built a new model (not pretty but works) but I can't find where to change the name 4016 New Macro to 4016. When I copy it into another schematic it changes to U6 New Macro. I tried to insert the .TSC but got a File Type Not Valid message. How do I send a TSC if needed?
A tweak would be better than what I have now for the OPA211-HT and I would appreciate it
Thanks again
.
Steve,
I believe you establish the name when you are using the New Macro Wizard. Chainging things once you have created the macro and symbol is a little daunting.
From your message it seems that you wnat to be able to place a part and have it labelled as "U# 4016", Is this correct?
If you can upload what you have I can take a look at it.
For the OPA211-HT I need to make a retraction. It appears we do not have a dedicated model to tweak for LTspice.
One option might be to use the Pspice model, TINA model and/or TINA ref design for its industrial cousin, the OPA211 that is spec'd for operation over -40C to +125C.
If you are interested, they are available on the device product page: http://focus.ti.com/docs/prod/folders/print/opa211.html#toolssoftware
You can see the notes section of the Pspice netlist (OPA211.mod) for a detailed list of model parameters that match silicon.
The notes say the model agrees with silicon over temp for slew rate and quiscent current.
The header in the TINA macromodel gives a detailed list of parameters that model meets over temp.
To look at the TINA netlist header choose the menu Insert -> Macro insert the macro opay211_tina-ti_spice_model-a.tsm that has been downloaded from the same page as the reference design.
Simply clicking on the symbol doesn't seem to select it, so select it by left-clicking and dragging the cursor over the symbol, like selecting multiple parts . Once the symbol is selected, then select File -> Enter Macro and the netlist viewer pops up in a separate window. There are some detailed notes in the netlist header that describe the model's accuracy with respect to the actual device. If the medel meets your requirements, you can run the usual sims in TINA while stepping temperature in increments over a specified range. For example, one scenario is running 1ms transient sim at temps of -40C, 0C, +125C.
Please let me know if you have any questions.
John
