is it possible to use this circuit from a 0804 output? i understand the output of the adc is 8 bit but how am i going to connect them to the bcd since it only has 4 inputs? should i connect the lsb to the second stage?
sorry if i'm trying to verify from you guys first before actually testing it. just trying to cut back cost here

the thing is i'm trying to avoid using pics and i'm sorry if no mention about that. it should be all hardware. truth is your suggestion gave me an idea how to implement this via software other than using truth table. first converting the binary to decimal then break them down to thre bcds. for the benefit of learning however i rather stick to hardware approach for now.
hi,
The lower 4bit nibble of the 8bit output from the 0804, is from 00 to Fh, ie; 0 thru 15 decimal, if you connect this to a 7seg decoder IC you will only see 0 to 9 displayed, the A thru F binary values will be blanks.
This also applies to the upper nibble... sorry its a no go..
