Dear Engineer,

I spent my two days reading the datasheet of ADN2848 again and again , I still don't know how it works .Here is my questions:

1. If my LD needs Ibias=100mA ,how do I set it? By setting which pin or pins of ADN2848?

2. What is the relationship between the Imod and the data we input through DATAN/P?

3.If my LD needs Pav=30mW, how do I set it? By setting which pin or pins of ADN2848?

4.How does the Impd influence the Imod and Ibias?In  the datasheet , a paragraph describs that it tell nothing about how to control.Here is the paragraph:

Thanks,and look forward to your answer.
