This is a question about the markings on LM3886TF chips.
I am looking at LM3886TF chips on ebay. The photos show NS cases, marked with two strings: "LM3886TF" in all cases; and then a second string which varies: "PM79AK", or "JM17AFE3", or "PM35AF".
The second string (the one that is not "LM3886TF"), might indicate production run or something else.
My question is does anyone know what that second string means and where I might find docs or discussion of the merits of one chip version over the other.
--
My question is motivated from that in the CPU world there have been times when a particular run of a CPU model was a superior over-clocker or had exceptional power consumption behaviour.
Perhaps this second string printed on the LM3886TF case carries info of a similar nature?
