Mistake in the IC_Linear Library

[nicolas8BQ92]

Hi,

FIY there is a mistake in the IC_Linear library that is provided with Fusion 360, on the AD822 SOIC schematic component, pin 3 ad 2 are inverted compared to the manufacturer provided datasheet. One of my designs for which I disdn't check confirms that the Datasheet is the correct one.

Hi @nicolas8BQ92 ,

I hope you're doing well. I've passed this along to our library developers for review.

Let me know if there's anything else I can do for you.

Best Regards,

HI, Thank you for your quick reaction, you may want to temporarily remove this component as a quick action. This mistake costed our company time and money and I wouldn't want others to end up the same way.

Best Regards,

Hello,
This issue can also be found in Symbol: "OPAMP-1" of the same IC_Linear library.
Pin + and - are inverted, which leads to wiring all TL072 inputs in reverse!

I would advise to review the whole library for similar issues, an official library shouldn't have such errors which, as mentioned before, costs time and money to anyone using it.

Best regards

Hi @andre.goncalvesY3M87 ,

I've passed this along to our librarian. The symbol doesn't have pads assigned to it directly so how can the pins be reversed? Did you compare it against the pin out of the TL072 component? Our librarian will follow up.

Best Regards,

Hello,
Thanks for following up on this.
They are inverted as they are labeled + & - but the labels position don't match the pin names,
in the image notice the pin name is "-IN" but the pin selected is the one next to the + label.

Best regards

Thanks for bringing this to our attention. We're investigating the issue, and you can reference ticket FUS-259834 when communicating with Autodesk to find out more. Once the status of this will change, there will be a follow-up forum post made.

I don't see an issue (unless recently got fixed):

Notice everything matches up perfectly

YES you do have to verify the symbol pins map to the proper pads  --otherwise SEVERE hidden chaos

Hi everyone,

Thank you for bringing this to our attention.

For AD822, the pin-to-pad mappings are correct, and the symbol itself is also correct. However, it differs from the datasheet representation because the datasheet uses positional pin placement, whereas the Fusion libraries use functional pin placement.

For the "OPAMP-1" symbol, the + and − signs were inadvertently swapped.

However, the pin names and pin-to-pad mappings were correct.

This issue has been resolved in the latest v34 release.

Maybe confusion---this (correct) symbol came directly from the fusion-provide lib:

there is no error whatsoever with this part.

what part are you showing in msg#9??

[frijo.francis0912]

MSG#9 shows the "OPAMP-1" symbol in the latest IC_Linear library which is v34. 

Here is the latest version of AD822

@nnovotney The one you are showing is a previous version of the same part.
