OPA990: Inquiry about changes to the silk screen marking on opa990

Adrian Liu

Part Number: OPA990

Hi team, could you provide the latest PCN for OPA990?

Customer wants to confirm whether we have added or changed the manufacturing plant for this device, as they have noticed some differences in the silk screen marking on the chip surface compared to before.

Hi Adrian,

That would likely be found in the datasheet. Do you know which package the customer is referring to?

Thank,

PCN#20180322004 does not apply the OPA990, but is shows that changing the font to OCR-A is made deliberately, without any other changes.

Hi Robet,

It should be the SOT-23(6)

Hi Adrian,

Well I learned something new today! Yes there was a symbol marking change on the devices! That information can be found here: https://media.digikey.com/pdf/PCNs/Texas%20Instruments/PCN20201016001.0.pdf

That document shows both the old and new versions of the symbols!

Let me know if that answers the customer's problem!

Best Regards,

Robert Clifton
