The TA2020-020 is the only verion of that IC that I know of.

It's not 2 different chips. TA2020 is the common abbreviation for the chip's full name, ie. TA2020-020.

In this sale on ebay. They show both chips...

I'm inclined to think the top one is a (possibly chinese made) fake as there has never existed an official chip called TA2020 without the -020 ending.

Here a link to the official specification for the chip. www.kafka.elektroda.eu/pdf/tripath/TA2020.pdf and as you can see, the name of the chip is offically TA2020-020, and that is what must be printed on the chip for it to be a real Tripath designed product.

As you look closely at these photos you can see that the top one ise exact copy of the bottom one and the marking "TA2020" is done by image manipulation (Photoshop, MSPaint, etc.). The bottom image is original.

It's not exact copies of eachother though. The second line, the batch number is different. So I doubt it's image manipulation. The top one is (very likely) a fake, though.

EDIT: To settle this once and for all, I checked all my TA2020s that I have accumulated over the years and all of them, except a non-functional chinese made fake reads: TA2020-020. The non-functioning chinese fake reads: TA2020 without the -020 ending. The chinese made fake still reads: Korea as origin, btw.

Please note the different font used on the batch numbers. It's hard to spot but it is, besides the missing -020 ending, what gives away the fake one.

If already making a fake I wounder why not make it completely identical to the original.

Saturnus said that for him only "ta2020" chips without "-20" marking were faulty and proven to be fakes. Is this the only fake you know of? Are there chips today with the complete "ta2020-20" marking which are also fakes?
