You might like to consider the MAX5136 dual 16 bit DAC.

I've never used it but Farnell just suggested it as a replacement for some AD DACS that I just bought.

It's pretty cheap, doesn't look as good as the AD part but might be worth considering.

Great documentation of your thorough design approach and the items you found important. I learned quite a bit. Not having an electronics background I have always wondered how equivalent the datasheets are when it comes to min, max, and typical values - that is whether they use the same statistical definitions, tests, etc. At the same time I have always figured that TI, AD and the like could be trusted as they have reputations that they want to uphold.
