serial data transmission, here i was trying to make a 16-bit frame from 8-bit ADCs. the ADC i want to use is ADC0801 and i have tryied to study study the data sheet but still i got a challenge.
the major problem is about sampling,we found some where he use separate circuit for sampling the analog signal but on other case he connect the signal directly to the ADC. so i fail to recognize which one is more correct... so please if you have any idea help me..

 

Since I don't know what the two circuits are I don't understand you question. Please post the two circuit configurations you described.

 

here is the circuit
