• AD7694

    请教一下,更换全新的同型号AD7694板子检测通不过,换回原来AD7694的就可以,这是怎么回事呢,可以直接更换吗,谢谢

  • AD7694 wrong readings

    Dear all,

    I use an AD7694 for reading from current amplifiert of an BLDC which is driven with 20khz PWM.

    50% of readings from AD7694 are right and good but the other 50% give me very high velues.

    Normal are results around 47000 digits but in case of wrong…

  • Ad7694输出为F

    在使用Ad7694采集数据的时候,当输入电压比较大的时候输出数据的后四位就一直是F不会变了。换了新的片子也是一样。程序也改过,还是一样的后4位一直是F。用示波器sdo确定Ad9694输出的就是F。请发各位有没有遇到这样的问题。怎么解决呢?还是片子本身就是有这问题。

  • AD7694电路及串口传输

    AD的精英们,我有问题需要解决,麻烦帮我看看 !

    电路目的:将陀螺仪的输出电压进行AD转换发送给ARM

    陀螺仪:ADXRS610

    AD芯片:AD7694

    陀螺仪和AD芯片的基准电压源:REF195

    运放:AD8031

    电路图如下:

    其中AD7694的2号脚接入陀螺仪的输出信号(之间有AD8031运放连接),我按照AD7694的时序进行读取,为什么读取的数值一直是0呢?

    我电路有问题导致采集到的就是0V?可是我用电压表测了AD7694的输入引脚电压的确有2.5v左右(陀螺仪不动输出信号就是2…

    Dear Karen

    Thank you very much for your advice.

    But in your case, the system side needs to use a higher clock.

    Then total system power might be increase.

         It will work, but the performance might be degread.

  • RE: ADC with really "True differential input"

    Thank you for replies.

    As I see in data sheet ADC with pseudo-differerential input couldn`t convert voltage below GND.

    For example AD7694. -IN should be connected to GND, and +IN should be between GND and VREF.

    So I can't convert negative voltage…

    Thank you for the quick reply.  Please let me clarify my previous statements.

    I am working on revamping a control circuit.  Previously everything was done in parallel.  I am converting to a serial design to decrease wiring.  My main goal is to match the…
