To build on what Russ said in his last paragraph, gyroscopic drift can be a real problem if you're trying to keep track of how far you've turned. I don't think it's possible to eleminate it completely. Some people has coupled a gyro with a compass for navigation, but if you're using the gyro for closed loop drive control then that isn't necessary.

In the specs I can read "±300°/s Single Chip Yaw Rate". This means that if I have one robot that turn 360º in one second, the gyro don't work?

My understanding of this issue is that the gyro will still work just fine, just maybe not how you're expecting it to work. What I mean is, the gyro will still output the voltage corresponding to it's max turn rate (300 deg/s), but you have no way of knowing if it's turning faster then that because it can't output a higher voltage.
I don't know what kind of application you are using this in, but be advised that these gyros have a really high impedance, which could affect the value your device is reading it's voltage at. To use one of these with my PIC I had to use a buffer amplifier in-between.
