• About AD7328 ADC misuse

    Dear Responsible,

    In my research project i used AD7328 ADC in order to readout unipolar analog signals.

    SPI digital communication was isolated by using ADUM3481.

    During prototyping i noticed that digital isolator was broken. After a long search period…

  • AD7328: Overoltage protection

    How must I protect input terminals of AD7328 from overvoltage (like +o- 40V).

     

    Applying +/-40V to the analog input channel of the AD7328 exceeds the absolute
    max ratings for the part. We have not included any extra over voltage
    protection circuitry…

    Wrote a code like this, but it doesn't work. What am I doing wrong? Tell me please. thanks

    #define cs_low() (GPIOD->BSRR = GPIO_BSRR_BR2)

    #define cs_high() (GPIOD->BSRR = GPIO_BSRR_BS2)


    #define AD7328_WRITE (1 << 15)
    #define AD7328_READ…

  • What am I doing wrong with AD7328

    please tell me what am I doing wrong? thanks

    Here is my code

    #define cs_low() (GPIOD->BSRR = GPIO_BSRR_BR2)
    #define cs_high() (GPIOD->BSRR = GPIO_BSRR_BS2)

  • AD7328读不到值问题

    我使用SPI传输模式用mode2(CPOL=1,CPHA=0),SCLK频率500kHz,t2 3.1us,t9、t10是1us。

    下面图1,我用AD7328的pin脚接法,我用arduino传输SPI,并且用arduino的3.3V接脚供电给Vdrive、VCC,VDD和Vin用电源供应器供电。

    图2,传送的指令为0b1011111111100000,设定范围。
    图3,传送的指令为0b1000010000110000,读值。

    我使用回圈重复传送图1与图2指令(或者1次图2,只重复图3),读到的DOUT如图4…

  • AD7328 REF IN/OUT Capacitor allowable error

    Hi,

    I have a question about the AD7328.

    What is the allowable error for the 680nF capacitor attached to the REF IN / OUT pin?
    Is it okay to attach a capacitor with a tolerance of ± 20%?

    Best regards

    Yuya
