We are designing to put your AD8557 Instrumentation Amplifier.
So I have a question for this.
Can I drive AD8557 with +/-3.3V or +/-5.5V dual-power supply(positive and negative) or not?
I can find Vdd and Vss on your datasheet AD8557 http://www.analog.com/static/imported-files/data_sheets/AD8557.pdf.
Th fig on page 13 show Vsy(Suply voltage)+/-2.5V.
This means that +/- power supply is OK,I think.
Otherwise can AD8557 drive only single supply voltage 2.7V to 5.5V, correct also this??
Please give me your good comment!
