• RE: Request Schematic Review about AD9258-125 and ADA4937-1

    Hello,

    Schematic for the AD9258 looks good.  If they seeking better linearity performance, they may consider using another amplifier since ADA4937-1 linearity performance falls off between 120-180 MHz.   Perhaps the ADA4939 would provide better linearity…

  • RE: AD8132, AD8138 ,AD4932 在3.3V供电时可以输入2v p-p信号吗

    谢谢你的建议,ADA4939-1 输出摆幅0.8-2.5V,完全够用,因为0.7v-2.7v不是运放的输出信号摆幅,而是输入信号,  运放如果增益为1,共模为3.3v/2=1.65v, 差分输出信号,每个输出摆幅是  1.65 +/- 0.5 v, 处于范围之内,请问ADA4939-1 输入信号的电压范围应该参考哪个参数?0.7v-2.7v作为输入的话,ADA4939-1 会有性能上的损失吗

    作为应用工程师,我们经常遇到各种有关差分输入型高速模数转换器(ADC)的驱动问题。事实上,选择正确的ADC驱动器和配置机具挑战性。为了使鲁棒性ADC电路设计多少容易些,我们汇编了一套通用“路障”及解决方案,希望能够帮助到大家。

  • AD4817-2 use as a multiplexor

    Hello,

    We are planning to use the ADA4817 1GHz Fast fet op-amp (amazing device that it is!). We would like to use it as a 2:1 multiplexor.

    We note that it can be powered down (with Iq = 1mA), however there is no information on the output topology when…

  • Driver amplifier for AD9257

    I just had a closer look at the AD9257, and found that you recommend using the
    - ADA4927-2
    - ADA4937-2
    - ADA4938-2
    as driver amplifier.

    Why do you not recommend the ADA4932-2? I like the ADA4932-2, because the dual
    package…
  • RE: 怎么理解1LSB(最低位)以内的模拟误差不会出现在输出端?

    我第一次听说是在ADI举办的一个网络研讨,关于差分驱动ADC的。

    他们就以这个理论作为ADC驱动器选择的一个标准,具体你可以参考研讨会的资料。
