Hi, Does anyone have the datasheet of the TDA4918G of Siemens / Infineon? It was produced in the 90's, but is obsolete now. Or maybe of the TDA4918A? Kind...

Hi all, I have a chip that has the ST logo on it and two numbers: 2904 and 9420. Its an 8-pin SOIC package. I am assuming the 2904 is the date code. I did a...

Bob, I think you may have the part and date code swapped. The part reeks of a LM2904, which is a dual low power single supply op-amp in a SO-8 package. I could...

I have to agree with Tony. 9420 is a typical date code (week 20 in 1994) while 2904 does not make sense as date code (week 4 in 1929 or 2029???). And a voltage...
