Lenka,

In what way did it fail to work?

Hello Ron, thank you for your answer. The behaviour is described and evidenced in the attached pdf. We tried it as follower or amplifier with separate supplies and also with linkage supplies. The linkage supplying did not work as seemed in Output pdf files. Thank you for your help.

Lenka,

Can you supply a Ti-Tina file?

Hello, Ron,

we are using OrCAD Pspice Designer . Do you want to send source files? Lenka

Model forum support,

I do not have tools to test the files. Please assist.

Hi, Ron,

How I can assist you?

It seems to us that the model falls when we use the growing power for operational amplifier, just as in our application we need. The model is working, when the supply is constant.

Hi Lenka,

I was made aware today that we never closed this post. I apologize for that. I looked at the files that you have provided and they are missing some PSpice directories/files because of which I am unable to simulate these. Can you provide us the complete directory so we can simulate the design on our end and identify the problem.

Thanks,
Nikhil

Hi Lenka,

I am struggling to understand the problem. Similar to Nikhil's post reply, I think we need more complete directory so that we can assist you further.

Hi, Herman,

thank you for your interest to solve our problem. I am sending you whole direkctory with the simulation designs. Please, do not hesitate to ask me for other files when you need them. Regards LenkaTI_technical_support.zip

Hi Lenka,

Here is an example of a complete Capture/Pspice project we need to help you further:
www.ti.com/.../sbom137

BTW, which cadence/capture version are you using? 16.2? 16.6? 17.0?

Also, perhaps try to describe again what you think as the problem? I look at your past post and the plots you provided and it seems to me the TLV341 behaves as expected as the unity gain since you configure it in unity gain configuration. So I guess I am not 100% sure what the problem is.

Hi Herman,
the main problem is:
the Schema Schematic_with_NCS2001_TS331.sxsch is going well during simulation and when I change NCS2001 with TLV342 then the same simulation schema does not work and these errors occure:

*** ERROR *** Can not find DC operating point - Non-convergence pseudo transient analysis

*** WARNING *** model "FK350601.FK350601 'Unknown parameter' XQC"
*** WARNING *** model "FK350601.FK350601 'Unknown parameter" XTI "
*** WARNING *** model "FK350601.FK350601 'Unknown parameter' TLEV"
*** WARNING *** Model "FK350601.FK350601 'Unknown parameter' TLEVC"
The difference bis using the TLV342 as NA2.

We do not understand why the simulator reports an error in the COMPONENTS, which have not been changed.

The use of simulation program:
Simetrix / Simpilis for Release 8.00C, build # 38
www.simetrix.co.uk
and this programm does not have opj file.

Used Operating system:
W7 professional

Used computer:
Dell Vostro I7-3612QM 2.1 CPU @ 2.1 GHz 8 GB RAM
Thank you for your interest and help. Lenka
