AD8293G80 Figure 6 and (Figure 9).

An answer to this question will be academic because I have worked around the potential limitations.  But I like to hear the explanation the datasheet does not explain these two figure and I guess most engineers don't read the text anyway which in my experience can get you very unstuck and if it is ambiguous will do anyway.

Thank you for being a member of EngineerZone.  Mentioning GLADION for assistance. 

Hi andrew-lohmann@home ,

Figure 6 shows the operating range of AD8293G80. For this figure, there are two conditions: (1) the blue one is the operating region for Vcc=5V and (2) the pink one is the operating region for Vcc=2.7V. 

As for your application, I added it below the operating region for your part:

In this region, the AD8293 operates in the linear region specified by the datasheet, and you should ensure that the application is inside this region. Thank you.

Regards,

Gilbeys

Thanks for your expliaination.  Of cause yes I see now.  I was reading the box as an exclusion zone.
