How to convert Pspice model to LTspice model for TAS5411-Q1

Other Parts Discussed in Thread: TAS5411-Q1, TINA-TI

Hi,

My customer want to use spice model by using LT Spice.

I found following thread which have similar question, but this specializes for Power IC.

https://e2e.ti.com/support/development_tools/webench_design_center/f/234/t/351072

My customer want to use TAS5411-Q1 Audio AMP IC, so could you please confirm TI can perform same responce as Power IC ?

Best Regards,

Machida

    Machida-san,

    Yes. This particular signal chain model is also encrypted. Please note that TI is not allowed to use or debug LTSpice issues when using TI PSpice models in LTSpice. The EULA prohibits us from using LTSpice for our products.

    There is a TINA-TI model and reference design available that your customer could use.

    Hi Britt-san,

    Thank you for your reply.
    Yes, I understand that TI is not allowed to use other spice model in general.
    But, If customer have NDA with TI, I understand un-encrypted model may be provided.

    However, from your comment, at first I will try to ask customer to use TINA-TI.
    Then, I want you to confirm about below.

    * Do you have information about difference b/w LTspice and TINA-TI ?

    BR,

    Machida-san,

    LTSpice and TINA-TI are two distinctly different simulators.

    Both are SPICE based simulation engines with IC macro models built into the tool (LTC devices in LTSpice, TI devices in TINA-TI). Both have a GUI (however, they are very different) and both are available for free download. Neither has a node limitation and both have the capability to import PSpice models and use them in simulations.

    Both perform well, however, LTSpice is particularly fast when using built in devices. TINA-TI appears to be faster when using an imported PSpice model. These are just my observations. I have used both simulators previously.
