A dual DAC…

March 1, 2011 | My Projects | By: Mark VandeWettering

My experimentation with oscilloscope displays made me wonder what the oscilloscope clock by Sparkfun/Dutchtronix used. It turns out to be a $5 dual parallel input DAC from Analog Devices, even available as a 20 pin PDIP. It can apparently do 833K samples per second, making it quite a bit faster than a conventional sound card like I was using. Archived for future playing.
