OPA2837: Unencrypted model

Gerald

Part Number: OPA2837
Other Parts Discussed in Thread: OPA837, TINA-TI

Hi Experts,

Our customer asked if the OPA2837 Tina Spice model work in Pspice. He said that he would actually prefer if the model can be converted into working into LTspice.

I have already pointed him to this FAQ below:

(+) [FAQ] TINA/Spice: Note about encrypted models and importing models from one simulator to another - Simulation, hardware & system design tools forum - Simulation, hardware & system design tools - TI E2E support forums

Now, we would like to ask if we have an unencrypted model that we can share with our customer for this device?

Thank you and best regards,
Gerald

Well Gerald, why don't you use the OPA837 model,

Hi Gerald,

the "OPA837.LIB" file which you can find here

OPA837 TINA-TI Spice Model (Rev. B)

can easily be imported into LTSpice:

Also read this guidance on how to import a "*.LIB" file into LTSpice:

Hello Gerald,

Michael & Kai have both proposed solutions for you. While TI recommends using PSPICE for TI or TINA-TI for simulating with our parts, there are methods (as described in this thread) for adopting the model parameters into a different SPICE-based software.

There are benefits to using PSPICE for TI and TINA-TI, but it is up to your customer to evaluate which simulation software serves their needs. If they encounter issues with the model files, please recommend they try the same models in PSPICE for TI and TINA-TI to confirm model functionality.

Best,

Amplifiers
