Since the OPA627 is prone to being a counterfeit when bought through alternative channels, I was wondering if it would be helpful to you guys if I were to maintain a list of datecodes of genuine OPA627s I come across at work from now on.
After having been confronted in the past with counterfeit OPA627s, the company I work for nowadays only orders them from a reliable (authorized) supplier. That fact together with successful tests on the instruments they're used in make it fairly certain that they are the real deal.
We use the following versions:
OPA627AP (plastic DIP);
OPA627AM (TO-99 metal);
OPA627BP (plastic DIP);
OPA627AU (SOIC).
Most of them will be the BP followed by the AU and occasionally the AM and AP versions.
We're talking of 1000-2000 OPA627s a year, bought in smaller batches, so we get to use quite some different datecodes. It's little effort for me to post them here, if you're interested.
