• RE: Can AD9643 sample DC signals

    Yes, the AD9643 can support DC-80MHz analog inputs. Please refer to example circuits in AD9643 datasheet figures 47 & 48.

    The analog input of ad9643 evaluation board is a 1:1 transformer. Is the differential line impedance from the transformer to the chip end controlled as differential 50 ohms in PCB design? But looking at the Gerber file of the evaluation board, it seems…

    AD9643 have two  pin configurations, Parallel LVDS  and  Multiplexed (Even/Odd) LVDS; Which one do AD9643BCPZ-250 belong to?

  • AD9643

    从数据手册看,AD9643芯片有两种管脚定义方式, Parallel LVDS 和 Multiplexed (Even/Odd) LVDS 。请问AD9643BCPZ-250属于哪一种管脚定义方式?

    Hi,

    i am working on AD9643 ADC, i am not able to do the data output from this fro different input voltages as per the table11 given in datasheet.

    i used a formula

    DATAin decimal=(applied input volatge*2^14)/1.75

    am getting

    Dear  Sir/Madam,

    I wonder how to use AD9634 to switch betwee 0-1V and -1V~1V, is there any solution for it.

    Thanks.

  • Use “AD9643-250EBZ” for AD6649

    The AD6649 product page includes “AD9643-250EBZ” as the Evaluation Board.
    Can the AD9643-250EBZ be used for AD6649 evaluation as well as AD9643?
    Do evaluators need to prepare AD6649 separately?

    Best regards
