New project: 24-bit, 1 Msps DAQ with SFDR up to 120 dB (w/ decimation). I'm pretty sure that everything can go wrong will go wrong even if it comes directly from the reference design, as this kind of circuits is basically a PCB layout exam problem. I'd call it a win if I can see the -60 dBc harmonics from my vintage HP 204C sine wave generator, which would mean that I got at least 12 bits in my first attempt.
