• 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 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 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).…

  • AD8428 Electrode interface

    Hi,

    I am trying to replace op-amp with an AD8428 in-amp, it will be connected to two electrodes that there impedance change when a  particle passes between them, the current design excite the electrodes using 100V DC and capture the drop in voltage through…

  • SPICE-model AD8428...???

    Hi, everybody!

    Where to take SPICE-model AD8428...???

  • 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 SPICE model not working

    Hi all,

    I have recently tried to run a simple simulation of the AD8428. I have downloaded the model, imported into LTSpice and run a simple transient simulation. The problem here is that the output does not amplify the input signal, but it stays constant…

  • AD8428:  Total harmonic distortion (THD) specification

    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?

     

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