 +1 Informative		 #119572 - high precision!!
Responding to: ???'s previous message
24 bits would be extrely high-precision!!

You are talking under 60 parts per (US) billion!!!

Do you actually have an input with that precision??

You entire input stage will need to exceed that precision if you don't want to make a total nonsense of the "24-bit" spec!
That means that all sources of error, distortion, noise etc must be kept well below 60 parts per billion.

Are your analogue design skills up to the challenge...?
