• DDS using AD5390?

    Is it possible to do DDS with the AD5390 or do I need additional components. I would really like to use the AD5390 as it has 16 channels with simultaneous update. 

    Thank you in advance. 

  • using AD5390 in SPI mode when DCEN is not connected

    Hi, I am working with a legacy circuit in which the AD5390's DCEN/AD1 input was not tied either high or low. The design was suppose to operate in standalone mode for an SPI bus. Is there any guarantee that the AD5390 will operate in SPI standalone mode…

  • AD5390 and I2C ?

    Hi,

    Does anybody have tried to use I2C bus with a AD5390 ?

    I'm trying to do so with a raspberry pi but got no answer from e device.  I have other

    devices connected to the bus which are answering (DS1631, DS3231M), I'm using

    wiringpi library…

  • RE: Amplification of output voltage

    Hi Ken,

    I apologize, I had a mistype in my previous response. I believe he is using the AD5930 instead of the AD5390.

    Thanks,

  • RE: SPI Interface to AD5390

    Hi Sasha,

    A few items that you could check:

    • On SPI (1), the A_N/B (bit 24) should be set to "0" when toggle mode is disabled.
    • You should not toggle the CLR pin every time you send an SPI frame.
    • The data should be valid on the falling…
  • AD5390 in daisy chain mode

    I am trying to access the DAC that has daisy chain mode enabled. I can communicate with it when it disabled. The communication path is fine.

    Once daisy chain is enabled there is no response from the DAC at all.

    Would it be possible for anyone to give…

  • AD5390输出为0无法正常输出,Reset后正常

    我正在使用AD5390,通过SPI驱动,驱动时会首先Init芯片(一般只在上电时做一次),然后设置电压输出。有一次同事在测试中突然发现输出电压不对,用万用表测量发现其中2块板子的所有通道输出为0,但是芯片的SFR和x1寄存器的返回值和我设置的都完全一致,输出却始终为0。最后通过断电再上电,芯片输出才正常。后来我连接了12块板子,连续测试了40多个小时,输出都是正常的,这说明我的驱动和板子稳定性是没有问题的。我现在怀疑是芯片偶然进入了Power-Down状态,但是我没法读出芯片到底处在什么状态。因为我的应用是隔几秒改变一次电压值…
