Hi , i 'm trying to convert an analog signal to digital (with an AD7703 and 8051) , this analog signal is coming from a welding generator with a capacitive discharge sparking system . If you can help me to protect electronics from electrical parasits.
Thanks in advance .
If you want to be even more paranoid, seperate the A/D conversion board from the rest of your digital logic, and then send the output of the digital side through opto-isolators.
