Hi all, As a part of the Autonomous Helicopter Project that I am working on, I am going to be designing a test circuit which reads the output of an acceleromter using a 16-bit ADC. I've done 8-bit ADC before, but not higher resolutions. Besides the obvious things of having a stable, clean power supply with decoupling, good ground plane, short interconnects, and low-pass-filtering the ADC input to limit noise and alaising, what else do I have to watch out for? Can anyone give me any pointers or app notes to look at? BTW, in case you are interested, we finally have a (very basic) web site up for the project. Take a look at: http://dylan.mae.cornell.edu Please realize that this is running on our workstation and is sometimes down.
