• ad9778

    hi,

    ad9778 is an high speed 14 bit dac,

    Ireference of the dac is 12ma when i use 100 ohms at i120 pin of it, so in oreder to find a full scale current of the dac i need dac gain , gain of the dac is 10 bit that can be set by reg 0A,0C, for i phase…

  • AD9778 Input Clock Harmonics

    Hiya,

    I'm using an AD9778 and AD9779, both on custom PCBs. They are both running with the default register settings (with the exception of register 0 set to 0x80 to enable the bi-directional serial interface). As such the internal PLL is disabled, so…

  • RE: AD9779 and AD9779A_Difference between the two products

    Hello ,

    Hope you are safe and well. 

    Kindly refer to the DIFFERENCES BETWEEN AD9776/AD9778/ AD9779 AND AD9776A/AD9778A/AD9779A section on page 25 of  AD9779A Data sheet. 

    Thanks,

    Lorenz

  • RE: I am using AD9778A dac for IQ modulation.

    We need to knoa a lot more information about what mode you are trying to use the AD9778 in to be able to help you. Are you using our eval board that include a quadrature modulator? Or is the AD9778 on your PCB. Please let us know what

    data rate, what…

  • RE: Measure SNR of DAC

    Can you explain what mode you are using the AD9776 ( interpolation and filter modes used) and give some details on data sample rate, output frequency of itnerest what results are you seeing and under what operating conditions.

    We spec SFDR and NSD but…

  • 高速ADC/DAC设计回顾

    摘自:电子系统设计

      着数字信号处理技术的迅速发展以及数字信号处理器件性能的全面提高,实际系统对高速数据转换器的要求也越来越高。例如,在移动通讯基站设计中,高速数据转换器不仅要有很高的转换速度,而且还需要对高频信号具有很小的噪音失真,以免小信号被频率相近的大信号所掩盖。对于数码相机和摄像机等图像采集和显示应用,为减少体积、成本并延长电池使用时间,高速数据转换器的小体积和低功耗也凸现重要。这些都对采用高速A/D、D/A转换器的电子系统设计提出了更多挑战。

      在《电子系统设计》专题论坛中,我们邀请到了两位高速A…
