• AD5734, does not manage to power up channel.

    Hello,

    I am trying to use a AD5734 on a custom board.

    I found this sequence on a other post, ad5754---no-output, it reveals two problems.

    The DVCC is up before the AVDD and the AVSS, around 5ms between DVCC and AVDD, then 2 ms later AVSS is up.

    CLR is…

  • RE: AD4734的输出怎么不对,默认四个通道一起输出最大值,可是只有CD通道输出5V,AB通道是0V

    AD5734在上电后,最好reset一下,之后再写入配置寄存器,数据寄存器,然后更新

    可以参考一下AD5754的参考代码

  • Linux driver for AD5724 ?

    Hello,

    I understand that there is no linux driver for ad5724.

    I also don't find any linux driver for similar device from the same family (AD5724/AD5734/AD5754)

    Is there any idea how (and if) we can use  ad5724 with Linux ?

    Thank you,

  • RE: Need a DAC with 2 positive and negative outputs of max 1,5 V

    Hi Konstantin,

    Would you be able to share the schematics especially that which involved the AD5734. Also, could you specify how are you sending the words to the part? Would you be able to provide scope shots of the /SYNC, SDIN, and SCLK lines?

    Regards…

  • RE: AD5754 - no output

    Hi,

    The reason why you read zero from the register is that the required output range was not set and has a default setting of unipolar 5V range. It is also important to note that all DAC channels on power-down mode by default and will ignore any writes…

  • AD5724 Write issue

    Hello,

    We have a write issue after power up. The first write to set the output range is sometimes ignored. We found that to write twice has improvement. The digital input pins are pull-up to DVCC on the board. So, DVCC and digital inputs become high…

  • a problem with AD5734AREZ output range

    We are using AD5734AREZ in our design and it seems that there are some problem with the output range. In the firmware, I configure it as +10.8 V output, however some times the output will be 5V once I power on the board. It does not happen very often…
