Strain gauge amplifier that also provides the strain gauge excitation voltage??

I heard some where a while back that you get a strain gauge amplifier (instrumentation amp) that can also supply the strain gauge with an excitation voltage. Is this true? How good does it work?

 

We used to use an AD620 and currently we have an AD8221 in our new design, unless we can find this "one-chip" solution.

 

If not, any suggestions for a method for an accurate (not super precise) excitation voltage?
