• RE: Looking for Space Grade DAC (preferably dual channel)  for QPSK modulator

    We currently have 2 space qualified high-speed DACs. the AD768 and the AD9731.  Both of these are single DACs.

    DA 评估板 可否自己FPGA提供时序控制和数据输入?

    型号:

     

    EVAL-AD768
    EVAL-AD9788
    EVAL-AD5546

     

    我想用其DA芯片,不想自己画板PCB,可以自己直接用评估板代替吗?

  • RE: 我在用AD8099时发生了振荡,如何消除?

    你好,我是按照AD768数据手册中的Figure 27来设计电路的,这样的电路连接应该也可以吧?因为电路板已经做完了,要把电路连接改成Figure 25那样的比较困难。

  • RE: AD5621BKSZ

    Hi,

    Let me clarify your question,

    We do not test any standard component for X-ray emissions.. within aerospace applications there are two DACs that probably may suit you, AD768S and AD9731s...

    in general, the X-ray is nothing else that ionizing radiation…

  • RE: Precision 16Bit,  True 4MSPS DAC

    When I use your links - for high speed DAC and only parameter I want to choice from is settling time, I find times 11ns, 20ns, 25ns, 35ns and next step is 2,5us, when I use another param - resolution - best chice is http://www.analog.com/en/products/digital…

  • AD8099 oscillation

    Hi,

    I use AD8099 as the output buffer of the AD768, for getting a ±1.1V output voltage. Specific circuit is in the attachment.

    When I test this circuit, I found AD8099 is oscillating. Is there any suggestion to eliminate the oscillation of AD8099?

  • AD9712 general recommendations

    We want to update our application based on AD9712 . What we need is indicated
    on page 7 of AD9712 datasheet. We checked AD9752 but we need to have > 3.5 Vout
    , and the total settling  time to 35ns( to reach 0,1 % error ). We need to add
    single…

  • RE: 超级干货——DAC接口基本原理

    DAC模拟输出考虑因素

    DAC的模拟输出可能是电压或电流。两者情况下,可能都需要知道输出阻抗。如果对电压 输出进行了缓冲,则输出阻抗将很低。而电流输出和未缓冲的电压输出将存在较高阻抗, 并还可能具有电抗性分量以及纯粹的电阻性分量。在有些DAC架构的输出结构中,输出阻 抗与DAC上的数字码字成函数关系,这点应会在数据手册中明确注明。

    理论上,电流输出应当连接到电阻为零欧姆的地电位。在实际应用中,该输出将采用非零 阻抗和电压。“顺从性”标题下只是定义了该输出可耐受的电压偏差大小,端接电流输出 DAC时应当注意到此项技术规格…
