AD5683 Headroom/Footroom Error

Hi,

 

About Figures 38 and 39 in the AD5683 data sheet,

I understand that a headroom error appears in the source load current state and
a footroom error appears in the sink load current state depending to the load current increase.

In the Figure 38, I accept it.
But in the Figure 39, it seems like a opposite direction of the load current that
a headroom error appears in the sink load current state (minus load current) and
a footroom error appears in the source load current state (plus load current).
Is my understanding right?

 

Best regards,

Nikkee
