ICs and hybrids pose as entire systems
The benefit of using highly integrated ICs is pure and simple: They do more of your work for you. This benefit is especially true of the analog front end of data-acquisition systems. ICs and hybrids that combine a multiplexer, a S/H amplifier, and an ADC reduce the time and effort you would otherwise devote to sensitive analog design. Not only do these chips free you from designing each analog stage, they shift the burden of testing--and guaranteeing--the entire system to the manufacturer.
However, these multichannel sampling ADCs may lack an important feature or not be flexible enough for your system. You have to ...
