If I am not wrong someone here on the forum said that they had removed the case from the LM9022 to have a peek at the chip inside (could have been many years ago this was done). I wonder if someone has made the same trick with these new chips? /Martin @Dmitry: A photo of the actual chip used w

Can you show any photos of the new chip, not only the whole wafer but the also a single chip in good resolution? What factory made the wafers and the chips and what factory put them in the SOIC capsules? /Martin On Tuesday, 10 April 2018 19:38:38 UTC+2, Dmitry Shevchenko wrote: > > 4" wafer pr

I'm speculating that most packaging houses only offer SMT-style packages. They are produced by the billions and have lower material costs than DIP due to smaller size alone. On top of that, leadframes for DIPs are probably in much shorter supply. -- You received this message because you are s

Judging from "datasheet" provided, it is really the same die as in old chips. It makes me wonder if these weren't created from leftover dies from old production, just packaged in different housing. Note that all the bad things about old chips are present here too: breakdown voltage of >60V, high
