• (AD8418)Which is faster device between AD8418 and AD8418A?

    Hi !

    I want to know which Tr/Tf is faster between AD8418 & AD8418A?


    At Figure.11 , it look like AD8418A is faster.

    But at Figure.15 & 17 , it look like AD8418 is faste.…

  • AD8418/A vs AD8210

    2 questions about AD8418 family,

    1. which P/N is recommended for new design AD8418 or AD8418A? We see our engineer do some improvement on AD8418A for timing parameter. Could you help us to check the difference between AD8418 and AD8418A?

    2.due to cost

  • AD8418, use with second amp to minimize Rsh?

    Hi there,

    I was just looking at the AD8418 part for an application in bidirectional current sensing in a brush DC motor drive.

    For this application, board size and part count are pretty sensitive, so this part looks pretty good.
    The only thing that I…

  • 关于AD8418应用的小问题


    要求为:输入电压9-16V,电流0-15A。假如采样电阻为0.02R,AD8418的参考电压为+3.3V,增益G=20,实际电流为10A,那么放大器输入电压0.02R*10A*G = 4V,这样AD8418的输出就饱和了,12位AD参考电压也为+3.3V,那岂不是输入到AD采样端的电压是4V,那就无法计算实际电流值。不知我上面的理解那里有问题。

  • AD8418 input common mode voltage


    Please let me know your advice about input common mode voltage range of AD8418 at 3.3V supply.

    Datasheet says below

    Supply range is 2.7V to 5.5V

    Input common mode voltage range is -2V ~70V at 5V supply.

    We can not find information of input…

  • 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…

  • AD8418 output not zero when no shunt current

    I'm using AD8418 to detect a LD current, but it normally keep a minimum output about 4mV when on shunt current, the Rshunt is 0.1 ohm.

  • AD8418 Pin#4 should be leaved NC or connected GND?


    According to AD8418 datasheet, Pin#4 should be NC. (It says "Do NOT connect to this pin.)

    But Evaluation board circuit, Pin#4 was connected to GND.

    Which one is correct?

    Thank you for your help in advance.

    Best regards,


  • What is a difference between AD8418 and AD8418A?


    I checked the AD8418 and A datasheet.

    Those are almost same, but those actual features seems a little different.

    What feature has improved?



    I checked again. Figure 3 to 25 are totally different. Slew rate , Gain vs Freq, bias current…
