adv7125 rset
Two questions:
In current-steering DAC, the current is convertered to voltage via the Rset. How to choose the value of it?
In the page2 of the ADV7125 datasheet (**broken link removed**), they choose 560ohm, the full scale current is I=Vref/Rset*K*(FFH)*4 and K=7.9896. What's the mean of the K and how to choose the value of K?
Thanks
