    Just a basic question...
    I wish to buy a BB OPA340NA opamps for a PSU I am designing.
    I did get samples from TI but buying from USA is a bit too much..shipping alone is 75 bucks to Maldives from Digikey.

    So I am going to china...:D.

    I like to know what you would chose between the two sellers I found.
    Seller 1.
    Seller 2.

    The BB datasheet says the Marking code is A40.
    Datasheet attached for reference.

    Why ?

    Seller does not show the actual image. For all I know he could be a reseller who places order from china

    Maybe it is not a question of who sells the stuff. Maybe it is a question of customer protection. You may pay more using ebay, but if seller fails to provide promised goods, then, does ebay offers you better protection than aliexpress?

    I note that both ali sellers that you linked are ranked 99% satisfaction, the ebay seller that bertus linked is 100% satisfaction. So only price and customer protection matters. Which organization provides better customer protection?

    Why does it cost $75 to ship to the Maldives? Is there no reliable distributor in India that you can use?
