Narrative:

On approach into charlotte runway 23; we were at flaps 3 and approaching the FAF lecar which is 2;500 MSL following a B757. Very suddenly the nose of the plane dropped followed by the right wing shooting straight up. I had my hands on the controls and I disconnected the autopilot and applied the maximum amount of aileron and full power. The airplane however kept rolling. We finally exited the wake at a nose low attitude. I broke off the approach and the first officer requested a heading and altitude from clt tower/approach. We climbed to 4;000 on a 120 heading and received delay vectors until we could sort out the extensive list of EICAS messages. I tried to re-engage the automation but we lost our air data. A short time later the EICAS shortened down to autothrottles fail; windshear fail; stall protection fail; and angle of attack limit fail. At this point the autopilot worked again but not the auto throttles. We cleaned up the plane and accelerated to 210 KTS. I then called back to the flight attendants to check on the situation in the cabin. Everyone fortunately had their seat belts on and was fine. I made a cabin PA to the passengers; then the first officer ran the associated QRH items associated with each of the EICAS messages. The first officer entered the new V speeds; reloaded the approach; ran another descent checklist; then we requested vectors back to runway 23. On the ground we received ads 2 (air data system) fail; ads 3 fail messages.
