In recent issues, Analog Dialogue has dealt extensively with topics in shielding and grounding,[1,2] emphasizing the techniques needed to protect the integrity and precision of analog signals in the dc and audio-frequency domain from interfering signals, whether at line frequency or at much higher frequencies. To complement those articles, we suggest here the elements of good practice for high-resolution “video speed” converters, i.e., converters of 10-bit or greater resolution, operating at word rates above 1 MHz 7 s' [& X7 E5 q n% L8 A3 X( \----------------------------------------- / ~5 O!
