OPA211-EP: file to simulate it

servan antoine

Part Number: OPA211-EP
Other Parts Discussed in Thread: INA129-EP, OPA211, INA129, TINA-TI, PSPICE-FOR-TI

Hello,

I need to simulate several components like the OPA211-EP and the INA129-EP. I can't find the files to simulate them. I can only find the version without -EP.

Do you know if it's possible to obtain the files?

If not, is it possible to modify the modelling of the OPA211 to that of the OPA211-EP?

Thanks

Antoine

HI Antoine,

The TINA-TI or PSPICE for TI macro-models use the typical performance parameter specifications, and do not simulate the min/max specifications, hence you can use the OPA211 or INA129 model for simulations.

Hi Luis,

I work on pscpice do you have the files for this software?

Thank you

Hi Antoine,

We offer macro-models for PSPICE-FOR-TI and TINA-TI. Both models are on the product landing page. On the specific device product page, select the "Design & development" tab and then select "Design tools & simulation" tab. For example:

https://www.ti.com/product/OPA211

Here are the links for the PSPICE-FOR-TI models for OPAx211 and INA129.

Hi Luis,

Thank you for these files.

When simulating a circuit, I would like to modify the voltage offset and current offset of the component, do you know how to do this ? (for the OPAx211)

Thank you

Antoine

Hi Antoine,

Our macro-models show TYPICAL performance and thus we do NOT recommend modifying them. If you really want to do this, do NOT change the model netlist but instead make any modifications ONLY using external sources as shown below.

Below I have attached OPA211 Tina-TI file for your convenience.
