    Could not find it in the datasheet!!!

  • AD7794: FAQs

    Q 

    Is there any way of getting the firmware in the microcontroller to control the
    SPI communication (SPI-USB Bridge)?

     

    A 

    We cannot supply the source code for the firmware. This is a canned routine
    that we use.

    We have the LabView source code and…

  • AD7794问题

        我们使用AD7794BRUZ遇到些问题，请协助查找原因。谢谢。

        用AD7794测量四路压力和一路重量，正常时电流50mA，在将砝码挂到称重计上时（砝码和称重计接触，其他金属物品也会出问题，绝缘物品不会出问题），有很大几率致使AD7794停止工作。表现为读出数据异常，电流上升至很大（1A以上，甚至更高），不能自行恢复正常，给AD7794发复位指令也不能恢复正常，且不及时断电，时间稍长可能导致AD7794损坏，怀疑是AD7794发生闩锁。

        请协助查找原因及解决方法。

        期待您的回复，尽早解决此问题…

  • AD7794 采样零电平 值为0.6V

    电路图如下

    现在能读取AD7794的寄存器的数据，跟手册一样， 当我将以系统地接到P5-,华东变阻器分压接到P5+, 发现0电平的时候采样回来时0.6V 。

    我配置是模式单次采样 PSW接地。  放大倍数为1 。采样频率为100ms.  

    如果我不接外部滑动变阻器，仅用1k电阻 接到P5+, P5- ,值是0.

    请问这个0.6v 怎么出来的

  • AD7794 External Voltage

    Hello 

    I want to use an external voltage of 3.3V for AD7794 to fully capture the signal.

    Which voltage reference component you suggest me to choose?

    And should I connect the REFIN- pin to the GND? 

    Thank you.

  • AD7794/AD7795

    Hi all ;

    I would like to design a loadcell reader and pressure reader; in   our old control card we used to use AD7705 ; but now I think AD7794/95 is better ; it is six channels ;

    I confused about which one is the 24bits resolution 94 or 95?

  • AD7794: RMS noise spec

    Q 

    There is an information in AD7794 Data Sheet: RMS noise: 80 nV (Gain = 64). And
    there is an information in Product Description and presentation about AD779x:
    40 nV (Gain = 64). What is true?

     

    A 

    The rms noise is 80nV when the gain equals 64 and the…

  • Offset value for AD7794

    Hi
    I got some formulae for AD7794 to calculate the data register value using offset and full scale register values.
    When i applied the same values of offset register, full scale register, and mode of operation to my evaluation board of AD7794, I am getting…
