• AD7908 Voltage problem

    Hello,

    I am using AD7908 in one of our designs. I am providing 5V at AVDD input ( Pin-5,6) and 3.3V at VDRIVE input (Pin-19). Please refer below picture. I have 24V-5V power supply and 5V-3.3V power supply on my board.

    When i turned off 3.3V power supply…

  • RE: ad7928读写控制问题

    您好!

    不能正常读到数据请先检查硬件设计,看硬件设计是否正确,硬件设计请参考附件内AD7928评估板原理图。确保硬件设计正确后,请检查焊接是否正常,通常虚焊或短路会导致芯片状态不正常。

    对于软件部分的检查,首先应保证初始化流程与数据手册中流程要求一致。在数字读写时,则应保证读写时序遵守数据手册中时序图。

  • Problem of AD7908.

    Hi ,

    I use the AD7908 and the current sensor IC "MAX4073T" without any OP between current sensor output and Vin of AD7908.

    In some case, the output of current sensor will be 0.4V, but there is a 3.6V rising due to the reverse current of ADC…

  • AD7908 full scale value

    Hello.

    For the conversion output of the AD7908, the value at full scale input fluctuates.
    The AD value changes according to the voltage of the previous channel.
    Measured at 5 V full scale.
    Condition 1 VIN 1 = 5 V, VIN 2 = 5 V AD value 255
    Condition 2 VIN…

    Hi-

    I moved this question about the AD7908 to the Precision ADCs community.  Someone there should be able to help.

  • RE: AD7357 how to check the DC Accuracy in worst case condition

    Hi Kevin,

    I have attached some list of ADC that were Automotive Qualified. Do you have specific paramater that you are looking for an ADC? like Throughput rate, no. of channels, or Resolution.

    You can also visit the Analog Devices website and filter…

  • SPI question on BF526

    I'm trying to get the bf526 to talk to the AD7908 over SPI.  It looks like I need CPOL = 1 and CPHA = 0, but when I choose this setting my select line stops going low when I'm trying to do a write.  The 526 manual says that when CPHA = 0, the SPI…
