Hey guys,
I am new to this group and I am desperatly looking for the footprints of 4 Analog Device ICs. Is there anyone helping me on how to find the footprint libraries for Layout of Orcad? the ICs are: AD8331ARQ,AD630AR,AD588BQ.
thanks so much,
Pariah
If you can find the library, you can find the library editor. Don't trust someone else's footprints. Heck, don't even trust your own till you have made a working board an and allocated the blame.

On 28/11/2005 the venerable snipped-for-privacy@gmail.com etched in runes:
A quick google on AD8331 turned up the Analog Devices data sheet with the QSOP20 (RS20) package perfectly detailed.
It's worth a try.

This is a perennial type of post.
Due to the differences in (it seems) everyone's needs (number of layers, keepouts etc), there is no such thing as a 'standard' footprint (well, perhaps most passives might have them but even so...).
So the short answer is, if it isn't already in a library, make your own. Note that making your own footprints will not only make you more competent with the layout tool, it can (under some circumstances) also help you understand placing/routing requirements.
Cheers

The only slightly odd part is the AD8331ARQ. The other two parts are standard and can be found in the Orcad Layout standard libraries installed with Layout. The AR and BQ devices can be found in the DIPxxx and SOx libraries. You should also learn to make your own footprints! Layout version 10.x has a nice footprint generator.

WOW. thank you guys.. that was a lot of help. I am trying to make the footprints by myself. cheers, Golnaz
