• ADA4941-1: DIS Pin and noise calculation

    In 17th page of ADA4941-1's datasheet, it gives how to calculate the noise,
    like below figure shown. I am not sure why there is a factor "2" and "4", as
    below red circle indicate:


    The 2 comes from the difference…
  • ADA4941-1

    Hi All,
    I am looking for OPAMP which can convert single ended signal to differential signal to drive the ADC which has differential input. I have selected ADA4941-1 and tested for -2 and +2 gain configurations which are mentioned in Figure 58 and Figure…

  • ADA4941-1 Is the phase of the differential output internally adjusted?


    I would like to use ADA4941-1.

    So, I have a question. Please help me.


    Referring to the D / S of the ADA4941-1,

    the internal circuit consists of two operational amplifiers,

    each of which has an inverting and noninverting…

  • RE: ADA4941-1 outputs in-phase... cause?

    Hi Wojtek,

    Your circuit using ADA4941-1 should work fine. I tried it thru simulations and it is not in-phase. Could you make sure that the contacts are clean? I mean no short-circuits. And could I have your pcb layout please? Just to make sure.


  • ADA4941-1 输出电压差分失调问题

    ADA4941 技术文档中提到,输出可能出现ֶ差分失调,并举了输出VOP=3.5V和VON=1.5V的例子。现在我的电路中也出现了这个问题,请问是怎么造成的,应该如何消除?
