Is this a genuine TI product? (THS3091)

Other Parts Discussed in Thread: THS3091, THS3092, THS3121

Hello!

My name is Jason.

Currently, I am using some TI products on my development board.

But I want to know whether current THS3091 is really a genuine TI product or not.

Someone insist that current THS3091 is not a genuine product.

(He believe that this THS3091 is a fake one from China.)

I use THS3901 and THS3092 on the same board.

And laser marking is different from each other.

Could you check following THS3091 product on your side?

Please refer to following image.

Thanks for your help in advance.

Best regards,

Jason

  • Hello Jason,

      Please give me a day or two while I check it out. Can you please let me know why you suspect the THS3091 is not genuine based on marking? How about performance? Does that work okay? The THS3091 is a very high-performance amplifier so reproducing its specs would be challenging. That's an easy way to confirm.

  • Dear Samir,

    Thanks for your feedback.
    Unfortunately, I am not in chrage of hardware design.
    Currently, THS3091 does not work correctly. Over current problem occurs all the time.
    Of course H/W design can be a problem.
    However, the board worked well after hardware engineer changed the part from THS3091 to THS3121.
    This is the reason why he suspects THS3091 is not an original TI product.
    And he insist that the chip marking of THS3091 is quite different from normal TI products.
    Please let me know if you need more information.

    Best regards,
    Jason
  • Jason,
    I think you are correct. The part does look to be counterfeit. I am going to get in touch with someone from TI who can help out under such circumstances.
