• AD8206 NC terminal

    Hi

    I would like to make sure about connection between PIN4(NC) and a die .

    If it is open then the circuit can trace on the PIN4 .

    Fig4 - I am trying to measure a solar bus with maximum of 1000VDC and 30Amps using a shunt of 0.003. I have grounded both Vref1…

  • Which is the best between AD8206 and AD8213?

    I'd like to measure the current of my resistive load (V=48Vdc, I=4A, Rload=12 ohm, Rshunt=0.04 ohm) and I'm thinking to use AD8206 or AD8213.

    I could use AD8213 because it allows to set the low-pass filter and it has the buffered output voltage…

  • AD8418/AD8206/etc Vref current, noise rejection?

    I am considering the AD8418 or similar device for bidirectional current measurement. One option is to connect Vref1 directly to Vs (positive supply) as shown in Figure 1 of the data sheet, but I am concerned about the effect of noise from the supply into…

  • (AD8206/AD8211)Why did you change the datasheet?

    Hi !

    I have some questions about ADI datasheet.

    Our team are checking the datasheet because if the datasheet was changed we have to explain the changes.

    And today , we found many datasheet was changed.

    For just one example , AD8206 datasheet was changed…

  • 关于AD8206标定和使用的几个问题

    ADI公司工程师:
      
       您好!
      
    我在使用和调试AD8206这款芯片的过程中,遇到了一些问题,希望得到你们的帮助和解答。

      1.AD8206数据手册上标注的输入失调电压指的是共模输入失调还是差摸输入失调?

      2.使用信号源给芯片加差分输入,信号源的低电平信号端与AD8206的1号引脚连接,并且共系统的地,此时如果信号源的高电平信号端与AD8206的8号引脚连接,则在该连接点测不到相应的差分信号;而如果将两者断开,则在信号源的高电平信号端能够测到相应的差分信号。这是什么原因呢?

      3.如果需要检测和标定ad8206的直流和交流输入误差…

  • (AD8206)Can you tell me the bias current when the VCM = 0V

    Hi!

     

    Thank you for your support everyday.

    I already asked about AD8418A and AD8207 bias current at the past session.

    (AD8418A)Vout ≠ Vref 

    (AD8207) Is the input bias current is matched?

  • 用AD8206做无刷电机相电流检测,很容易出现烧毁的情况!求解!

    用AD8206做无刷电机相电流检测,很容易出现烧毁的情况!

    做一个无刷控制系统,要求检测相电流,采用AD8206实现,并实现电流保护。系统电源电压要求是50V,设计的持续电流200A,瞬间电流600A为保护点;电路采用手册中典型的应用接线;实际做完板测试时发现,在电源电压40V左右时很容易出现烧毁的情况,烧毁的现象是,IN+,IN-都对地阻值降低,VREF引脚对地阻值也降低,有时还出现VREF引脚直接与地短接的。。。另外,用手触摸IC也会出现坏的情况;总之感觉这个IC很容易就出现损害;具体原因的不明白…

  • (AD8418A)Vout ≠ Vref

    Hi !

    I have a question about AD8418A.

    This is my test circuit.

    I measured the Output voltage but it is not Vref level.

    => I don't have AD8418A so I measured AD8418.

    Why this happens?

    Our customer said that  this won't happen when they…
