• No reply from AD74412R

    I am trying to establish SPI communications to a Mikrow AD-SWIO board containing an AD7412R. This board is recommended by AD as a third-party solution on the AD74412R device page.

    I am unable to get it to respond to my SPI commands. I am attempting to…

  • AD74412R Analog ground and digital ground

    The reference schematics for the AD74412R evaluation board do not show a separate analog ground plane with a single connecting point to the digital ground plane.     On previous analog designs I usually have a separate analog ground plane from the digit…

  • AD74412R SPI Port connectivity

    Hi just a question on the AD74412R SPI port, I assume that the /SYNC pin is comparable to the device chip select?? It also appears that it is not possible to connect multi AD74412R devices upto a single SPI interface and use separate /SYNC signals to control…

     I am trying to establish SPI communications to a Mikrow AD-SWIO board containing an AD7412R. I am unable to get it to respond to my SPI commands. I am attempting to follow the read back mode procedure in the data sheet and while I think I am issuing the…

  • AD74412R RTD Calibration Method for 0-20k ohm measurement range?

    Hi,

    We want to use resistance measurement for PT100, PT1000, NTC10k, NTC20k. Is there an internal application note for calibration of RTD measurements for AD74412R? 

    Accuracy of AD74412R for resistances between 80ohm and 20k ohm is around %0.3. We need…

  • AD74412R ADC conversion control registers

    Hello,

    I am working on  AD74412R configurable ADC/DAC IC. I am having problem in initializing and configuring the input mode(ADC). It converts the first channel with correct value but the rest of channels ADC results return incorrect results. The steps I…

  • ad74412r的CURRENT INPUT EXTERNALLY POWERED模式下adc值异常

    ad74412r的其他模式下,工作正常,adc值读取符合预期。

    但是在CURRENT INPUT EXTERNALLY POWERED模式下adc值异常,当外接电源输出1-4ma时(即ad74412r输入电流为1-4ma时),读取的adc值的范围0x300至0xcb00。

    当电流在5-12ma时,adc的值基本为0。当电流为13-20ma时,adc又从0x1000上升到0xcb00范围。

  • Does the Evaluation software use or support the libIIO for accessing the AD74412r Linux driver

    Hi ,

    We are using the AD74412R chipset in our custom board running Linux. Have ported the AD74412/3 R protocol driver from ADI to the linux.

    Wanted to know if we could evaluate the chipset by integrating the IIO user space library in to linux and use…
