ADN2848 directly connect to a LD

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.

  • Dear Kate-DUT,

    You have opened three discussion threads at same time with the same ADN2848 application question. To help us control our records, please merge them together and refer to our answer in the thread titled "Circuit design issue of directly connect ADN2848 to LD".

    Best Regards,

  • Dear Dongfeng,

    Sorry for the trouble, I will merge them together right now.

    And hope we can keep in contact in e-mail for further discussing .

    Thanks for the answer very much.
