signal processing for medical application signals.....
(OP)
hi... got a question guys... i am working on a 16-bit ADC IC to convert analog signals of low amplitude and frequency. I am goin to use the dual-slope architecture. After some calculations, i discovered that the frequency of the clock needed is too high (MHZ)...So the idea is working on 8 bits at a time using the same architecture to reduce the clock frequency. Is this possible and how do you combine the 2 8 -bit data to get the 16 bits again?

both are 17 bit accurate -- and they are not.
What kind of sample rate do you need ? Any other limitation?

500 samples per second it not a very high acquition rate.
Over-range occurs when the input level exceeds the allowable input value of the ADC. Thus you get xFF as your output value.
