• AD7674 SPI Interface

    I am implementing AD7674 ADC in my application with SPI interface.

    I am designing board based on SPI interface.

    As per datasheet, for SPI interface below schematic is shown for reference.

    But I am not able to figure what would be status of other…

  • AD7674 / Single/Differential  Ended Configuration

    For Differential circuit as shown below , datasheet says

    " When provided an input signal of 0 to VREF, this configuration produces a differential
    ±VREF with midscale at VREF/2
    "

    For following configuration and different Analog input ranging…

  • AD7674基准电压相关问题

    AD7674芯片使用外部基准电压,在ADC工作的时候基准电压对地值会被拉低,ADC不工作的时候恢复正常。ADC摘掉基准电压也恢复正常。

    基准电压芯片位REF02,推测它的带载能力不够,在后面加了电压跟随电路。加入电压跟随电路后,基准电压正常工作,跟随电路输出电压会被拉低。

    请问如何解决?

  • ad7674: Read data when the board is used as a stand-alone board

    Problems with the Eval-AD7674 evaluation board.
    It is not possible to read data when the board is used as a stand-alone board.
    DBUSY (P2.33) and D11 (pin 22 of AD7674) have strange behaviour when the AD7674
    is working in mode 0> I can…

  • Example program for interfacing BF to simple parallel ADC

    Hello,

    I am interfacing an AD9224 ADC with a blackfin BF537 EZ-kit. Is there a working VisualDSP example on how to interface these 'simple' parallel-output ADC's that require no additional control to the PPI port? I would like to know this before I start…

  • RE: Is it a real breakthrough to remove the input voltage range limitation of IA

    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…
