What is a difference between AD8418 and AD8418A?

Hi

I checked the AD8418 and A datasheet.

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

What feature has improved?

Regards

I checked again. Figure 3 to 25 are totally different. Slew rate , Gain vs Freq, bias current and output sink current etc... Sorry, I misunderstood. Those are totally different circuit, I think. How come those are same name? Please tell us how to select A or non A. Those are for different application? Regards moto

    Thank you very much for prompt answer.

    the application that Common mode changes quicker.

    You mean, AD8418A is good for motor current measurement like as Figure 33 ?

    so, AD8418 is for High side sw? or low side sw, like s Figure 34,35.

    Thank you for your help.

    Figure34 and 35 also common mode change quickly when sw off. AD8418 is for Figure 36?
