I'm designing a portable instrument (a gas chromatograph) which outputs a +5V analog signal (referenced to ground) which I need to digitize to 16 bits resolution. I need a conversion rate of at least 100 sps and preferably an SPI interface. Most of these requirements are easily met but with devices having a very high conversion rate compared to what I need. If I pick such a fast device (for example LTC1864 from Linear) am I making a compromise on noise over one rated slower (maybe ~800sps) and which I am having difficulty in finding?
As this is a one-off and signal quality is very important, price is not a big consideration.
