I want to convert an 8-bit digital parallel signal using AD558 to analog. The 8-bit signal comes from an A/D converter that converts voltage of a temperature sensor. So the voltage keeps changing and so is the 8-bit signal. So basically, I convert an analog signal (voltage, keeps changing without particular order) from a sensor using A/D converter. Then the resulting parallel 8-bit is converted again into analog using AD558, a D/A converter which takes 8 parallel bits and produces voltage. That's basically the theory I have in mind now.
I'm wondering on one issue. The 8-bit parallel signal keeps changing every second. Are all the 8 bits of one particular data arrive at the AD558 at the same time? I mean, is there a possibility that the current 8 bits will be mixed up with the incoming 8 bits (since the voltage keeps changing, so there are different combinations of 8-bit data coming into the AD558)?
Or is it just as simple as connecting an A/D converter which produces 8-bit parallel then connect the A/D to the AD558?
Any theoretical explanation are really appreciated.
