1st thing why do u need 4 LDR?

2nd thing why r u using ADC0804?

 

if you want to get digital output from 4 LDRs then use ADC0809 that has 8 channels.

another option:  use micro controller with built in 8 channel ADC like AVR or PIC. ATmega16 is best.

 

finaly if you want to stick with ADC0804 then use 4x1analog  multiplaxer (not digital) before ADC.
