As always, the non inverting input impedance is 110k.

The inverting impedance under this condition is 10k.

This makes perfect sense. I tried, with no much success, Thevenin and
Kirchhoff for the common mode and differential impedances. I am going
to pick the brain of TI, and see what they say.

I was going to go through your analysis, but since you said it is
wrong I guess I will pass :^). I will take a look at it later tonight
to see what I can spot.

Thanks for the reply.
