I am designing sensor circuit using the AD8557.
I have two questions about this device.
1.Datasheet describes that AD8557 operates from single-supply voltage of 2.7V to 5.5V.
Can this device be used with ± power-supply? .
I think that it's ok ,however there are no specifications on datasheet.
2.Pls refer to the Fig40,41,42.
I cannot understand the meaning of this figure.
It would be greatly appreciated if advice could be gotten.
