• RE: AD7986 vs. AD7641

    Hi Shen,

        

         Good day

         As we can see, you are right that both AD7986 and AD7641 are very much alike. But the AD7986 is in PulSAR technology while the is a SAR. Although these are almost the same and PulSAR was created base from SAR technology. Please…

  • 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…

    Hi Yake,

    I have attached a list of some of the ADCs that fit your criteria of 2MSPS sampling rate or higher at resolution of 12bits or more.

    You may also wanted to check the ADI website and do a parametric search (http://www.analog.com/ps/psthandler…

    Hi Jebas,

    PLease see attached list of the ADIs some of the latest differential ADCs with less tahn 2 LSB INL error. I have short listed this ADCs for DAQ systems application. I have included in the column on the file the throughput rate and full power…

  • RE: ADC used for single-pulse conversion

    Hi Postino,

    Here are some list of ADC that could be suitable for your application. You may also wanted to check the ADI website and do a parametric search and put in parameters on the ADC that you wanted to search. Please refer to the link below.

  • Design a precision ADC front end for measuring small signals with high common mode voltage at 1MHz frequency?

    Hi, I want to build a electrical impedance measurement device using AD4003/AD4001, where a small current (around ~1mA, at 1MHz) is inject into the body and the difference voltage at two electrodes on the forehead is measured. The signal to be sampled is…

  • 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…
