Cannot find anything about this part

Hi team,

I have a customer looking for the part illustrated in the picture, he said it is supposed to be a logic component, but I cannot find anything related. He wants to find the datasheet or document for it and seek for the substitute. Could you help me about this?

Thanks!

Best Regards,

Jenny

Hello Jenny,

If you go to the Part Marking Lookup page: http://www.ti.com/packaging/docs/partlookup.tsp#divline , enter o2727a, the tool returns:

Part number	Marking	Package \| pins	Status	Description
OPA2727AID	O2727A 2727A	D \| 8	ACTIVE	e-trim20MHz, High Precision CMOS Operational Amplifier

You mentioned you thought it might be a logic component, does an OpAmp make sense? Here's the Product Folder page: http://www.ti.com/product/OPA2727/pinout-quality , and in fact this marking matches the description on page 15 of the datasheet.

At your service,

~Leonard

Hi Leonard,

Thank you very much. I supposed the first letter "0" not "O", so couldn't find answer.

Thanks again.

Regards,

Jenny

Hi Jenny,

Yes, I made that same assumption first time I tried it, as it does look more like '0' than 'o'.

Just curious, what is the purpose of identifying this particular component? I'm guessing you do not have a schematic, and probably not repairing this pcb, so my natural curiosity has piqued!
