I'm a novice when it come to electrical engineering and I may be missing a few key concepts but I'll try my best to respond to questions.
I have a "Low Cost 10-Bit Monolothic D/A Converter" (AD561J) that is in an arcade unit. I am attempting to inspect the data coming into the DAC using a logic analyzer with 8 leads. I'll have to do this for another DAC on the board which has an identical configuration.
What is the best way to convert these 10-bits that come in at the same time into a binary stream that I can then inspect with my logic analyzer?
DACY# correspond to the input pins. For example:
DACY1 - 0 DACY2 - 1 DACY3 - 1 DACY4 - 0 DACY5 - 1 DACY6 - 0 DACY7 - 1 DACY8 - 0 DACY9 - 1 DACY10 - 1
And the output:
Preferably as soon as all 10 inputs have been received. Looking at the datasheet for the DAC I don't see a clock input. How does the DAC know when to output the correct voltage, or is it always fluctuating as new bits come down the pipe?
Bottom line: How can I turn 10 digital inputs into one binary output, preserving the bit significance order?
Any help would be greatly appreciated!
