• AD7328

    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…

    please tell me what am I doing wrong? thanks

    Here is my code

  • AD7328 substrate


    Which N-well or P-well  is the substrate of AD7328 ?

    I can read that there is not the power sequence in AD7328 from aboslute maximum rateing.

    But, I think if the substrate is a n-well,  the first supply must be the most negative ,

    and  If the substrate…

  • 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

  • AD7328 problem

    Hello everyone,

    We are experiencing some problems with the ad7328 ADC converter. The problem is that the ad7328 burns out. This happens after some period of time (from 2 to  8 hours ) of perfect working of the converter (we have checked this with many…

  • AD7328 channel selection problem

    I am trying to get data from different channel of AD7328, but receiving data only from channel 0.

    This is my code.   How can I switch to different channel

    spi_data ( 0b00000000 ); // range_register1

    spi_data ( 0b00000000 );

    spi_data ( 0b00000000 );…

  • AD7328 resolution problem

    I am using AD7328 ADC with 12 bit resolution. I want to know about relation between reference voltage, input voltage and digital output.

    means if I am supplying 3 VDC to reference with input voltage 5 voltage what would be my digital output. 

  • AD7328 cpol and cpha spi ?

    Sir, how are you ?

    About the AD7328, where the DOUT frames ? Wich values to CPOL and CPHA ?
