    请问AD8429ARZ与AD8429BRZ  两者有什么区别??@

  • AD8429 voltage noise

    Is the maximum input voltage noise 1nV/rthz?

    In the data sheet, the 1nV looks like it is in the Max column (page 3), but I want to be sure

    that somebody didn't press the tab key accidentally.

    What are other people getting?

  • AD8221和AD8429

    在AN-683笔记(使用交流激励进行应变计测量)中,将AD8221更换为AD8429是否会更好?工作温度为-40~125。

  • AD8422和AD8429

    在50Hz交流mV信号放大中,相同放大倍数,相同外围电路下,AD8422到3.6mV时输出信号就开始不再正弦,AD8429到6mV后输出信号才发生变形,这是什么差别导致的呢。

  • AD8429 gain switching

    For a data acquisition frontend we need an instrumentation amplifier with wide bandwidth, low distortion, and low noise. We are considering the AD8429. The frontend needs to capture signals with +/-10V, 1V, and 100mV full-scale range, requiring to switch…

  • AD8429-AC coupled front-end

    Hi,

    I am using AD8429 (gain = 1000 )to make biopotential measurements. As I use AC coupled inputs, I add a resistor to ground as discussed in the datasheet. I also compare the measurements using a CMOS front-end commercial biopotential amplifier.

    The…

  • AD8429 offset voltage

    Hello,

    in my circuit I have a problem, with the offset voltage. I dont how is the best way to solve it.

    Below you can see my circuit.

    I have measurement the volteges Up, Un, Uref and Uout with different values of Rg. The relay are reed relay. My…

  • AD8429 Output Noise

    I am using the AD8429B for a low noise LED current sensing application.  I have a decent analysis and measurement where I calculate the noise and measure the noise.  The problem is I get discrepancies. 
     
    For both the noise analysis and measurements…
  • AD8429 noise problem

    Hello,

    I want look at noise of amplifier AD8429. I made a schematic (see Fig 1) and I did some experiments.

    Fig 1. Schematic

    EXPERIMENT 1

    Device is power off.

    Output noise is about 518uV (see waveform on Fig 2).

    I think, this is own noise of…

  • AD8429 for pH monitoring ?

    Hi All,

    I am trying to monitor pH from a low impedance sensor. The glass electrode is used as a reference.

    The input referred noise of the amplifier needs to be low as well. AD8429 seems to be the lowest noise option. AD8421 is another option which…
