  • AD8428:  Total harmonic distortion (THD) specification

    Q 

    My customer needs the total harmonic distortion (THD) parameters of the
    AD8428. Do you have this data or can you give some comments on it?

     

    A 

    Unfortunately, we decided not to specify THD parameters for this part. However,
    I can tell you…

  • 关于AD8428噪声问题 about noise of AD8428

      

    搭建了AD8428电路测试，射频信号源从反向端输入一个300K正弦信号，正向输入端接地，输出噪声很大，用示波器测试输出，波形抖动严重;即使是输入全部接地，依然有很大的噪声输出，请问是电路问题吗还是AD8428本身噪声问题，如何解决

    The AD8428 circuit test was built. The RF signal source input a 300K sinusoidal signal from the reverse end, and the forward input terminal…

  • AD8428 Bandwidth

    I have some questions about issues I have been having with the AD8428. In my application we are looking at lower microvolt(1-10µV) range at up to 4MHz frequency. We decided to use the AD8428 since it has pretty much the bandwidth we need(3.5MHz).…

  • INamp AD8428 output goes low

    Dear All,

    I am trying to amplify the voltage of a Wheatstone based resistive pressure sensor. I use AD8428 inamp with +Vs and -Vs connected to +15V and -15V from a precise DC supply. the reference pin is connected to the ground. The output of the pressure…

  • AD8428 Heating

    I am trying to design an IN AMP with gain 2000 Using AD8428 but my ic is overheating when i connect input voltage of 1mVpp and output is rectangular with 22Vpp.

    Is my IC is damage or there some problem in my connection?

  • AD8428 with intermittent floating inputs

    I have been using the AD8428 to amplify fast transient signals in the 10-100 uV range with microsecond time resolution. The AD8428 so far appears ideal for this purpose with settling time less than 1 us at a gain of 2000, but I seem to have destroyed one…
