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…
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).…
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…
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…
