• AD7986 External reference (Vref) typo? and connection queries

    using the AD7986 with an external reference configuration (with a +5V
    ADR435 ref) with PDREF=high and REFIN=low.

    first question is : how you connect my external reference buffer (AD8031) ?
    The REF pin and the BVDD pin should be connected together…

  • AD7986 vs. AD7641

    Can anyone tell me what is the major difference between these two chips?

    BTW: Is the SMA (SMB?) adapter in the attached picture included in the EVAL-AD7986 package?  If not, where can I get it?

    Thanks,

  • CPLD读取AD7986数据问题

    小弟目前在调试使用CPLD接收AD7986数据,转换结果总是读取不对。使用的VHDL语言,速率已经降得很低了,还是读不对。请大侠指点。

  • RE: ACE plugin for EVAL-AD7986FMCZ

    Hi DavidP,

    Unfortunately there is no ACE plugin yet developed for the EVAL-AD7986FMCZ.

    The AD4003 is a very similar product to the AD7986, being a differential, 18-bit, 2 MSPS SAR ADC. The AD4003 has better performance and comes in a smaller package size…

  • What type of converters can the ADA4807 drive?

    What type of converters can the ADA4807 drive?

     

    The low broadband noise of 3.1nV/rHz and the low distortion of -139dBc makes
    the ADA4807 an ideal option for driving 16 and 18 bit SAR converters such as
    the AD7980, AD7685/AD7686 and the AD7982…

  • RE: ADI工程师博客分享——如何正确驱动SAR ADC前端

    以下内容是网友就此新网络工具与 AnneM 的讨论,顺便也分享下~ 当然,你也可以就此工具提出自己的建议或意见哦

                   

    网友:这是一款很棒的工具!我想构建一个电阻抗测量设备,现在我需要为AD4001/AD4003设计一个ADC前端。将一个小电流(大约1mA,1MHz频率)注入人体(从左耳到右耳),我们需要测量前额上两个电极的差动电压。我认为要采样的信号是一个小信号(Vpp<1V),共模电压相对较大(从-10V到10V)。

    此工具中还没有AD400x,因此我转而选择AD7986和ADA4940…
