I have a task to design the cicuit for an 8-bit tracking Analog-to-Digital converter, the list of IC's we are suppose to use is:
74LS191 4-bit up/down Counter
LM311 Voltage Comparator
AD558 8-bit DAC
What i dont understand is, is it possible to create an 8 bit ADC converter using a 4-bit counter and if so how should the counter outputs be connected to the 8bit DAC inputs, or could we be supposed to use two 4-bit u/d counters if this is the case how should the 2 counters be linked together?
i'd appreciate any thoughts you all might have.
Thanks.
