AD News - Matched Pairs

An email from Analog Devices:

We wish to update you on the recent EOL notification for the MAT02, MAT04 and SSM2210 products. We are working on a process change to an existing ADI Wilmington bipolar process that will allow us to produce parts very close in performance to the existing MAT02/04 and SSM2210 devices. Because of the different process, the new parts will have new part numbers (MAT12 replacing MAT02 and MAT14 replacing MAT04, and SSM2212 replacing SSM2210).

The MAT12 will be available in a TO-78 can package. The SSM2212 will be available in a SOIC package, with PDIP still To be determined. We are projecting that all the new parts will come only in PbFree versions. Customers of present leaded versions are advised to move to Pbfree versions when the new products are available.

First wafers for MAT02/SSM2210 replacement are currently in fab on the new ADWil process with sampling dates in March. We estimate first production shipments of the MAT12 around June 2010. MAT04 will run 1-2 quarters behind MAT02/SSM2210 development.

We advise our customers to consider the MAT02, MAT04 and SSM2210 to be EOL as notified on the previous Notice, soon be replaced with the MAT12, MAT14 parts. We further advise our customers to take appropriate measures to ensure bridging inventories until such time that the new products can be qualified in their designs.

MAT02 not recommended for new designs. Replacement part MAT12 with samples available April 19, 2010.

This news could potentially make a lot of specialist OEMs happy. Let's hope the new parts perform at least as well as their predecessors.

Thanks for letting us know.

Semi-officially this has been around for some time (here too), good to know though that they haven't given up on it in the meantime...

PDIP is dying, like it or not. The wafers are one thing and the semi makers have that figured out as cheaply as possible on their end. But the packaging is a whole other story. We use an A-to-D which only comes in a DFN package. It's a 16-bit converter and it costs just over $1.00 each. They save so much money on the new packages. Sorry but get used to this. Side note - I have been to the AD wafer fab in Wilmington several times. My company had a piece of equipment installed there for 3 or 4 years. I never got to go into a clean room. But the whole facility is very cool. That is the only wafer fab left on the east coast of USA. Schweet. DW.

I prefer Freak Nasty's "Da Dip" remixed by PDIPPY

The datasheets are out (here and here). Just had a quick look, I couldn't spot any difference to the former parts specifications. Though, no samples yet, at least not as unimportant non-manufacturer.

PDIP is going going, virtually gone. The package itself costs more to manufacture, and to buy. (most Semi manufacturers buy packages from a vendor... as volume on PDIP goes down, it's less interesting for the vendors to make the package, and maintain their equipment... so cost goes up).

It's now time to get those SMD skills up to scratch. Really, it's not incredibly difficult (I promise). Prototyping in harder, but proto PCB's aren't as much of a challenge as they used to be, or as expensive. TSSOP (Thin SSOP package) pads can be etched with a lazer printer. (however, I prefer just to make the circuit in Eagle and get it built up with batchpcb.com)

Cheers

The 6386 will be available in a SOIC package, with Noval still To be determined.

Such a very amazing link!
Thanks you for the post.

So it looks like they are out now...all for the low, low price of $15 a pop. Jesus national, why did you have to stop making the LM394...

Ptown, do you have any 990 pcbs left? I have a couple leftover 394s that I'd like to put to use....
thanks!

MAT12 is higher spec'ed than the LM394. Use SSM2212 for low cost.

The package itself costs more to manufacture, and to buy.

Then I wonder why the new SOIC8 SSM2212 is much more expensive than the old DIP8 SSM2210.
