LME49720: LME49720NA: Fake or Authentic?

Hi Ee Heng Meng,

Welcome to E2E, thanks for your interest in our devices.
You need to buy our devices directly to TI or an official distributor in order to guarantee the authenticity of the devices.

Jose, thank you for your attention on this query.

I  was comparing these 2 reputatable component supplier for TI, yet actual photo of LME49720NA IC chip appears to be rather different. So I think it would be safer to refer to TI product manager, if can help advice it's customer about its product authenticity?

Appreciate and regards

Hi Ee,

where did you buy them?

Such scratches on the pins are not unusual. These can come from the machine which bends the pins after assembly.

Hi Ee Heng Meng,

I need to know where you bought them in order to consult someone else. As I mentioned we can guarantee the authenticity of the ICs if you didn't buy them directly from TI or an official distributor

Those 2 link are the component suppliers where I usually purchase TI parts - LME47920NA.

So are they TI authorized distributors?

Hello Kai,

I bought from RS components, they are not in listed as TI authorized supply network which Audio Engineer Jose provided

Hi Ee,

we here in Germany do also purchase products from TI from RS. We consider RS as reputable as Farnell.

Hi Ee Heng Meng,

It seems that RS is a huge company, but It seems that It is not a TI authorized supply network.
