  • Questions for your ADP5080

    Dear Sir/Madam,

    We are just studying your ADP5080.

    So I have some questions for you.

    1)Do you have the trace layout of evalboard?

      We would like to use for our reference design.

    2)If we dont use ch-7, then how should we deal any setting?

    3)If we…

  • Accuracy of the ADP5080 internal sequencer

    My customers are considering ADP 5080.
    ADP 5080 is equipped with an internal sequencer.
    For example, the delay time can be varied from 0 to 14 ms with EN_DLY 2 of the EN_DLY 12 register.

    What is the accuracy of this delay time?
    I think that it depends on…
