G'day all Quick question: I connect Vref+ of the F870 to say 2V. Does this now in = general mean I can (neglecting noise and LSB error) resolve an input = ranging from 0V to 2V (Vref+) to an accuracy of 2V/1024=3D2mV? I have = browsed the databook, and the above is my take on the issue. Anyone have = a different view? Ian Rozowsky Engineering Manager Centurion Systems P.O.
