Obviously, you have not done data acquisition before. It is
meaningless
to talk about sampling rates without stating the desired resolution.
It is like talking about velocity in terms of direction alone. I have
worked on research projects requiring real time A/D and none of them
have used the lowest resolution. Further, there is the SINAD of the
analog front end to consider when calculating 'true' resolution. Many
solutions exist to meet your needs. To provide you with an optimal
solution I need to know the following:
What is the physical parameter being measured?
How often does it need to be measured?
How many significant digits are required?
