• AD5426 DAC SPI通讯问题

    AD5426 DAC芯片通讯问题。

    REF_4V = 4.096V

    上电后,Vzero=-4.09V

    无法通过SPI通讯来控制DAC输出 Vzero一直为-4.09V,之前偶尔可以控制Vzero用 DAC复位至0V的指令。

    STM32中程序:

    void SPI2ADChipConfig(void)

    {

      GPIO_InitTypeDef   GPIO_InitStructure;

      SPI_InitTypeDef    SPI_InitStructure;

      RCC_APB1PeriphClockCmd…

  • RE: Setting the full scale current output of AD5426

    Many thanks for the clarification.

    I would like to ask, if I were to follow the application note AN-912, which DAC should I use ?? Can you please suggest one ?? They have showed two examples with 20mA DAC output current in the same application note.

  • Rising edge triggered clock and disable daisy chain on consecutive writes for the AD5426?

    For the AD5426,  I can't figure out how the control bits work on this device.  I've got a customer who wants to have a rising edge triggered clock and also wants to disable the SDO (daisy chain).  How does one do this?  The table of C3-C0 doesn't…

  • [征文] IN118的基准源用AD的芯片,上面写着D6B,困饶我很久了 AD5312


    这个芯片(AD9833)的名字我猜的,可忽略看,如果是这个芯片,左看右看也不知是干吗呢?

  • ADI芯片辨识、型号查找

  • Daisy chain issue with AD5415

    If you are using or plan to use the AD5415 12-bit DAC chip in a daisy-chain configuration, you need to read page 20 of the marked up data sheet attached.  If you are using the SDO output of even a single AD5415, then you also need to see the erratum marked…
