| Trying to Find an IC |

Hi, i guess this is the best place to post this so here goes...
Ive just found a load of IC's and i cant for the life of me find where they are from. Ive crawled all over the net and i cant find anything but dodgy "Let us find an IC for you" sites.
They are in a 8-Pin micro-SOIC package, they are made by Analog devices (thanks to the trusty logo), but on the front the have a strange accronym:
S V 8.
Thats it. Also on the back of the IC the number 0326 appears (presumably something to do with the package type) and on the outside of the plastic IC 'Tray' it says:
"Analog Devices Micro - SOIC - ADI - 0098 - 22"
Thats all the information that it gives. Anyone with a clue will be fantastic.
Thanks, Phil |

Contact your local sales office for Analog Devices and ask them to cross reference the package marking for you.
Or you might find a cross reference document for package marking to IC name on the Analog Devices web site.

Chances are they were custom packaged for a certain customer. I've been in the semi-conductor industry for 14 years and customers will want a common part packaged/stamped with 'their' part number so that nobody will know what part is on 'their' board. If this is the case Analog Devices won't tell you anything about that part.

Where did you find them ? Did you find them in the storage room
of your engineering department or did you find them on Ebay ?
The number 0326 is very likely a date code. It means they were made
in the 26th week of 2003. If they were in your engineering department's
storage room, and if no-one in the dept. knows anything about them,
they still had to be bought, so your purchasing department will have a
list of P.O.'s issued by Engineering. It has to be one that was issued
during the last two years. Shouldn't be too hard to track down.
If these are parts that no-one knows about, look for an employee who
quit. Call him, or find out what projects he was working on. Look
through his old papers.
If you just found these on Ebay, then I don't know.
The package type you gave is "8-pin Micro SOIC". Analog Devices
does have a package called "Micro SOIC", but I don't know if you
were speaking in a generic sense or if that's really what you have.
Their packages page is here:
http://www.analog.com/Analog_Root/Packages/Packages_Home/
If you were speaking in a generic sense you could measure the
package with a caliper and perhaps a microscope and find the type.
I could type in more, but I'm going to stop. |

Ok guys, thanks a lot.
As for the package, it is a Micro SOIC (aka. MSOIC) package.
As for the date code, i still do not know.
The code was a shorthand for the ADG619 SPDT analog switch. I rang up Analog devices in good old ireland and found out.
They said that the only referance to the package information was in the datasheet, and since i got the package number wrong  ( is was S V B, not S V 8) there was no chance of finding it. The rep said that analog were releasing a document that contained all abbreviations within the next few weeks because so many people were ringing up about them. Thanks,

Actually if you had posted that marking accurately, I would have been
able to find it. I did search for it, both on the net and on the AD site.
When I searched for SV8, of course it showed nothing.
Go to Google and type in this: "Analog Devices" SVB
The 2nd hit shows your device. |
