What is the closed-loop bandwidth of the INA143 at gain 0.1?
I would expect the gain-bandwidth product to be a constant, but it's worth comparing the two on the bench before designing it in (I suggest measuring both the gain-of-10 -3dB point and the gain-of-0.1 -3dB point to have a point of comparison with the datasheet limits). 

Note that the slew rate is typically a fairly good 5V/us, but you'll run into that at high amplitudes.
