It is called as a 24bit chip (I dont know why) For the very obvious reason that it gives you 24-bit values! but you will only get 12 to 14 bit of usable data, with excellent circuit board layout and lot of digital filtering. Yes there's the catch! The output data cannot ever be better than the input data! If you want a true 24-bit output, then all of your input must be stable, accurate, noise-free, etc to at least the equivalent of 24 bits - ie, 1 part in 16 million!! Yes, filtering can help, but... See this thread for example: http://www.8052.com/forum/read.phtml?id=134700 and many, many more... |
