Repair Burned Leonardo

I smoked a little IC in my Leonardo board connecting a 24V to a input IO pin... Please, don't ask why!!

According to specs, is an LM358 op amp (the one on the left side of Arduino Logo: http://arduino.cc/en/uploads/Main/ArduinoLeonardoFront_2.jpg).

Reading in internet i found that this IC is for the automatic power line selection between USB and external power supply. ¿Is there a way to remove this damaged part and replace it for a hard wire, fixed source selection?

The arduino board still operational in the way that i can upload sketches to it, but, of course, all the digital pins are wasted. I hope when i replace the op amp this lines will back to life again; Like as i said: i hope...

Many thx in advance.

Just chalk it up to a dumb mistake -- we all have made them --, learn from it, and buy a new one.

Agree with RoyK

That seems unlikely.
