I agree that delta-sigma is a good technique, and as I said, that's actually a pretty nice part. On the other hand, by your criterion, a PRBS generator is also a no-missing-codes ADC. If they'd billed it as a
21-bit ADC, which is what it is, that would be great.Cheers

No, a prbs thing usually misses one code.

It could be 100 bits:
1) I believe nothing TI says in their specs (S/N, anyone?) 2) It isn't at least 8k samples/second so is of no use
With 40dB S/N? ;-)
Clearly, the truth is not within you. You did reply (without even bothering to snip).
Symmetrical is 'prettier'.
Jeez, you're showing your age there. ;^)
I was hoping someone might have the answer for that! Another of life's mysteries solved.
Thanks.

Gee whiz, Phil. I was using 7 digit DMMs 25 years ago. Old tech now. And Fluke was selling 6-1/2 digit DMMs at the time, i trust that their accuracy was real. Of course warm up times were on the order of half a day (12 hours), easier to keep them running.
Funny, when considering your reply just above...
Joe, count the bits.

Not so funny, since you're the one telling us that you could not care less, yet clearly lying.

Since it was a decade counter 26 bits were used (one for signum) in the Flukes. The other used 30 at least. AND this tech was over 20 years ago. Getting 8-1/2 or 9-1/2 decimal digits may be technically feasible, but the measurement error sources are dominating the game at
6-1/2 digits already.
Yah. Try 22. Or you could try counting on your fingers and toes.
