Hello,

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.
  @Vsy=±2.5V
 I cannot understand the meaning of this figure.

 

It would be greatly appreciated if advice could be gotten.

 

Best Regards,
Kou
