The end for the gain clones? LM3886 obsolete?

That won't go down well.

Something odd going on with the TI site at the moment as well.

Anything LM3886 related is meeting with resistance:

Its looking that TI has made a decision to go full-on classD, they no longer have a category for classAB amps over 50W - the LM4766 for example is still listed but is hidden amongst the classD offerings. When you find an 'old style' classAB amp you're treated to a banner for the 'next generation' classD offerings with similar power outputs.

I'm wary of things like that tbh Jon. Remember the dual N and P channel lateral FET's. RS and Farnell had many hundreds available. I contacted the manufacturer and asked whether these parts would be recommended for a new design and whether there were plans to stop production. The answer was that they wouldn't not recommend them, and that if production stopped and there was demand that they would start production again. Within a month or so of that RS and Farnell had marked them obsolete and no stock available, presumably sitting on all the stock they have.

It is indeed concerning that the data sheet is now gone from TI's website. I sure hope that's just a glitch and not a sign of obsolescence. I haven't heard anything from the distributors. I usually get EOL notices on products I buy and haven't heard anything. The parts are still marked as Active (i.e. still in production) at Digikey, Mouser, et al.

I know there was a sizeable reorganization at TI recently. Maybe the LM3886 was transferred to another group and that prompted a website update where the LM3886 product page fell through the cracks.

Think about this. If a semiconductor company were to drop a chip without any warning, it would have huge consequences for their customers which would lead to all sorts of unpleasantry (law suits, etc.). There is a process -- notification is sent to all known customers as well as distributors, a 'last buy' date is set out in the future along with a last ship date. All of this is a many month process.

Unless someone can produce any evidence of these already having happened, the correct conclusion is that there is some hiccup in the web site.

Man, even on the weekends I'm working!

As far as I know, no one has killed the LM3886, this looks to be a website issue. Stuff like this can happen if someone is updating a datasheet (package / tape and real info / orderables, etc.) and flips the product folder to inactive accidentally.

On Monday I'll see what's going on. This device is supported by a product line in Dallas, and we all LOVE when other product lines find our hiccups 😉

The latest from my TI rep

I asked my TI guy about this, and he said:

Hi Dan,
I’m not sure what’s going on with the product folder on the website. I’ve sent an email to the marketing team to find out what happened.
The part still shows active in my system and it’s available for purchase on TI’s store.

Regards,
Mark

Marketing said it was a glitch. Nothing to worry about.
