Adam,

You might have better luck searching Digikey's database and either buying from them if you have some other stuff to make it up to the minimum order, or cross-checking with Mouser to see if they have the particular part. If you don't mind narrowing to a specific vendor a priori, you could also go straight to Analog Devices and use their parametric filters to pick out your chip. If you only need one or two, you might even just be able to get a sample from them.
