I received a new issue of Sensors. There is a new ad for a 24 bit A/D from Cirrus Logic. See http://www.cirrus.com BTW- I have been running the 16 bit Burr Brown A/D at an oversampling rate of 30 readings per sample. Someone mentioned on a previous listing that oversampling was the equivalent of a higher resolution A/D. I agree with the consept that multiple readings will give one a more accurate sample value but I wonder how I would get more than a count of =B1 32768 (higher than 16 bit) ? The only way I see this occuring is to take say 30 readings per sample and then only divide by 15 rather than 30. Is this a valid approach or mathmatical hocus pocus? Could the individual who wrote the way to calculate the effective A/D resolution with oversampling repost the way it's calculated.
