SMD Part Marking Code help, I have run out of ideas!

[KraigK]

I have a part that I know quite a bit about but just can't locate the datasheet. It is a 5-pin Op-Amp or Comparator, rail-to-rail, SOT-23 package or similar.

+V is 5V
-V is GND

A couple of chips are marked BCUU and another is BCWV so I figure BC is the base and the other two are date codes but I just can't locate this thing. It should not be an obsolete part.

Thanks for the help!

BCUU and BCWV may be SMT codes.

They're not unique, and may not have the meaning you think they have.

Check an SMD codebook. (you did read the sticky, right?) I checked one and didn't find it.

A lot of times when I get stuck on identifying parts, you have to start looking at the manufacturer of the product, and see if you can narrow-down what manufacturers supply the parts to that mfgr. Sometimes it's easier, when you can WHO made the
electronic part.

Yep, I did read it, I did most of that one day last for 8 hours and just kept getting dead ends. I'll check it again, maybe there's a resource I missed.

This is the last part I need to ID!!!

Took some better measurements, looks like a SOT-363 package.
