I do not know why at INA21x op amp, at figure 10 (page 11), they specify 4 different Vs without correlating them to the Graph's curves. Also, on the graph they plotted two red and two black lines on the V+ swing side and I guess they have something to do with the different Vs mentioned.
If these 4 Vs mentions were not there, I would assume \$ Vs = 5 \$, since this is what specifies at the beginning of the page 11.
My next guess is that, in order for them to make the plot, they had to draw the different currents, so instead of changing the Load resistor, they changed the input voltage. But this does not explain the double red/black lines.
- Why are multiple Vs mentioned?
- Why are two red and two black lines on the plot, at the V+ voltage swing?
- Do they (and how) correlate with each other?
