I have a new USB scope design using an AD9220AR or AD9220ARZ.
These are SOIC 28 pin parts.
The SOP 28 parts have a "s" in the name like AD9220ARS and AD9220ARSZ.
The SOP versions have pins on half the pitch of the SOIC so its imprtant I get it right.
Pretty much all the cheap Chinese vendors have the IC's marked wrong.
They are mostly selling AD9220AR and AD9220ARZ as SOP !
I managed to get a correct one from RS Components but at £20 a pop not viable for a production run.

The small pitch parts are SSOP (the first 'S' standing for 'shrunk'), I see on TB they sell the AR/ARZ labelled as 'SOP' (which you call SOIC) : https://item.taobao.com/item.htm?sp...QNo2yn&id=634154201840&ns=1&abbucket=0#detail. So I'd hazard that in China 'SOP' is synonymous with 'SOIC', certainly that's been my usage, SOP = 'small outline package'.
Incidentally, keep an eye on these guys, they look to be making cheap Chinese clones of ADI converters : https://www.relmon.com/en/index.php/list/10/35.html
