    The data sheet of AD8221 says it can be used both as a single and dual supply, however when i try with single supply (12 V ) to amplify a 100 mv signal (gain=1) the output is oscillating. with a dual supply (using voltage divider) it's working fine...
    Can anyone suggest me an In-Amp that can be used with single suupply....

    Thanks
