I'm planning to use the AD8221 as the instrumentation amp to amplify a  bridge input.  I want to be able to tell if the bridge has been  disconnected.  What will the output of the AD8221 do if the inputs are disconnected and allowed to float?  If it reliably swings into a rail,  then I should be in business.  Thanks.
