Hello Neil! Ah, yes - ADC's. A subject near and dear to my heart. As you may well know, analog to digital (and vice versa) signal processing is very common in present-day electronics, but not very easily understood. The upside is that our good friends at Texas Instruments have a website that is loaded with all kinds of information. Their home page is http://www.ti.com Rather than trying in my own feeble way to explain the process to you, I've found some links that will help. The first discusses data convertors in general using the Successive Approximation Register technique. Very good. The second takes you to their knowledge base for Application Journals. The February 2001 issue contains a much more detailed explaination of the SAR charge redistrubition process but, unfortunately, you'll have to come back to it at a later time because the Feb. 2001 issue hasn't been placed on the web yet (I get hard copies mailed to me). I hope this helps. If you need further info, contact me directly at: karlkolbus@ameritech.net. Your not-so-mad scientist, Karl http://w ww.ti.com/sc/docs/psheets/abstract/apps/slaa013.htm http://www.ti .com/sc/docs/apps/msp/journal/current.htm
