Hi guys i am in the process of trying to figure out how and where to start to build a Analog to digital converter for a project. I have done some research and it seems that at the basic level its nothing more that a pulse oscillator circuit followed by a comparator. The specification i must stick with are :
- max input freqeuncy 100khz
- successive approx type with best guess centering
- max bits are eight
- max error of 1% at output
If anyone can direct me to some circuit diagrams or information, i would appreicate it.
thanks peter
