WEBENCH® Tools/TINA-TI: LM3886

Part Number: TINA-TI
Other Parts Discussed in Thread: LM3886

Tool/software: WEBENCH® Design Tools

Dear Sir.
I am a beginner of TINA-TI, from Japan.
I configured a very simple amplifier of LM3886 on TINA-TI.
However, a error message appeared.

“TLD pin: INP does not match any pin of the macro component. {LM3886}”

I can't understand the meaning of this message, and what should I do?
By the way, there was no problem with other operational amplifiers.
Best regards.

    Hi,

    Something was wrong with LM3886 model in TINA library.

    Please go http://www.ti.com/product/LM3886/toolssoftware to download LM3886 TINA model. This one can work well. Thanks!

    Regards,

    Hao

    Thank you HAO, quick reply.
    Following your advice, I got 3 files: LM3886.lib, tld, TSM.
    But I'm a TINA-TI beginner, I'm very sorry, so
    I don't know how to compile these files into TINA-TI.
    Could you please instruct step by step?

    Regards,

    Hi,

    You can just download the LM3886 reference design TINA model. You can run the simulation in this reference design. Copy the device "LM3886" and paste it in your design should also work.

    Hello! HAO,

    Following your advice, I could download "LM3886 TINA-TI Reference Design (Rev. B)".
    I could run it on TINA-TI, and I could cut and past the LM3886 into another schematic and it worked fine.
    However, the high frequency stability of the copied LM3886 is more abnormally stable than the original one, therefore seems incorrect.
    However, I am able to modify the original circuit and simulate it, so I solved this issue for the time being.
    If there is a better way, please tell me.

    Thank you very much,

    Takayuki TANAKA

    Hi,Hao,

    I'm very sorry that there was a mistake in my circuit drawing.
    The copied LM3886 worked correctly.
    Thanks to you, this issue have solved.
