• AD8597 to Filter ADR440

    Dear Team,

    I would like to know more about the attached circuit Please share your thoughts.

    In this circuit, the output of ADR440 is filtered first using an active LPF and then using a passive LPF.

    The output of the 2nd filter is going to the I/P of an…

  • recommended ADC driver, external reference and reference buffer options?

    Q 

    What are the recommended ADC driver, external reference and reference buffer
    options?

     

    A 

    The AD7961 datasheet recommended ADC drivers are the two single-ended op amps
    ADA4899-1 and AD4897-1 or differential amplifier ADA4932-1. The low-noise,
    low-power…

  • AD5791: Recommended reference

    Q 

    1. For ADI's Reference chip, as below shown figure , Seems ADR423 and ADR440 is
    our best part, whose TC is 1 ppm, noise is 1 uVpp. The initial Accuracy is only
    0.05%, long-term stability is about 50 ppm.
    2. In the PPT file, we use AD5791 to…

  • RE: I need IBIS model for ADM1270

    Hi,

    You've posted on a wrong community forum.

    But here are the links where you should be posting your queries.

    1. For ADM1270 post it on Power By Linear.
    2. For ADR440 post it on Voltage References
    3. For ADG721 post it on Switches/Multiplexers.

  • RE: Suggestion for negative Vref

    Hi Kaos,

    We have only two references capable of negative output voltages at this time. These are the AD688 (+/- 10V) and the AD588 (+/- 10V, +/-5V). Neither are capable of a direct -4.096 V output.

  • RE: 请教：有关于AD7190通道转换的问题

    谢谢关注。

    通道转换后停顿500ms再次读取ADC效果是一样的.

    前端接入信号为100mV .使用ADR440做基准，双极性。

    不知道问题出在哪里，很茫然..

  • RE: Different conversion results using ADC0 and ADC1

    Attached are the schematics of our prototype.   The analog reference voltage is supplied by an ADR440 at 2.048V and AD5 is grounded on the detector board.

    If it appears that my issue is a hardware issue, can you give some guidance on the correct way to…

  • 最爱ADI放大器-ADA4817

         其实用过ADI的IC还是比较多的，没办法一一列出来，就说几个最近在用的，比如基准电压ADR361，ADR360，ADR440，ADR127等等，还有各种放大器，RRIO的精密运放AD8554，低Ib，高带宽，高压摆的电压反馈型ADA4817，超低输入偏置电流的AD549，用来做皮安表非常棒，也是超爱，还有其它一些年代比较久远忘记全名了，也懒得去查。

         现在说说我最爱的ADA4817，它的最大特点就是高带宽高压摆并且拥有超低输入偏置电流，带宽上G，压摆印象中是800V/us左右，输入偏置电流是pA级别的…

  • 最新方案文档推荐——医疗X射线成像解决方案

    医疗X射线成像检查的目的是识别病人身体中的异常情况或将病人归类为健康人群，同时最大程度地降低辐射影响。数字X射线(DR)和计算机断层扫描(CT)是最常用的X射线成像技术和应用。

    医疗X射线成像原理和典型架构

    DR和CT的基本工作原理相同：X射线束穿过人体，一部分X射线由内部结构吸收或散射，余下的X射线图案传输到检测器，用于电路和计算机进行记录或进一步处理。

    DR检测器：DR检测器包括闪烁晶体层、TFT面板、模拟数据采集系统和数字处理系统。闪烁晶体层将X射线光子转换为可见光子，TFT面板将可见光子转换为电子…
