    Hi Wilson,

    The Burr-Brown date code 25A8JH means that OPA2277 was most likely manufactured in May of 2022.  It could also be in 2012 or 2002 but considering it’s now 2023 it is highly unlikely.

    Having said that, buying any parts from unauthorized TI distributor runs a risk of obtaining counterfeited parts.
