Footprint AD8421-KGD

After looking for the SOIC box I found this reference. I think it would suit what I do.

I hope ii'll have the same characteristics as the AD8421-KGD.

Hi 206_RC,

Could you clarify if you're going to use the SOIC package or AD8421-KGD die only? If you want the SOIC package you can refer to the SOIC footprint you've shown. But if you need AD8421-KGD, the SOIC package will not be similar to AD8421-KGD, as AD8421-KGD is a known good die only. You can refer to the footprint shown in the datasheet:

Hi Kristine,

I don't know the meaning of 'known good die only' but I need the same specification (Noise, offset etc...) as the AD8421-KGD with the SOIC for my electronic circuit design.

Thank you  

Hi 206_RC,

AD8421-KGD is only a die product. It doesn't come with a specific package (like SOIC package). 

If you need an SOIC package for your design, I suggest you look at AD8421. The noise spec is the same with AD8421-KGD, and AD8421's offset specs are better.

I'm curious, could you share how did you select AD8421-KGD in the first place?

Kristine

Hi Kristine,

Thank you for this information. When I'm in Altium Designer and search the footprint. I haven't see the SOIC.

Or I can't download following the instructions. Normally, at this stage I directly have the right library.

after reading the DS I should have the SOIC footprint, but where ?

Hi 206_RC,

Have you checked out our ECAD model search? A SOIC package for AD8421 is available here: https://www.analog.com/en/design-center/packaging-quality-symbols-footprints/symbols-and-footprints.html

Hi Kristine,

Thank you for your helps, after clicking on your link, there are only 2 models for AD8421 : 

But only the model 'AD8421ARZ' is fit for me because it's in SOIC package. So I'll take this one for my PCB.
