Problems with a DIGITAL GYROSCOPE

[zuri]

I am working with the ITG-3200 gyroscope. My problem is that a expect an angular rate when the device is rotating around one of each axis. In addition, if the device isn´t rotating, I supouse that the output should be 0.

The truth is that I obtain the following outputs when the device is still:

x= 42 y= -110 z= -17
x= 44 y= -116 z= -16
x= 46 y= -108 z= -18
x= 47 y= -111 z= -18
x= 45 y= -111 z= -15
x= 48 y= -110 z= -15
x= 41 y= -112 z= -17
x= 44 y= -106 z= -19
x= 46 y= -112 z= -15
x= 45 y= -108 z= -17
x= 46 y= -110 z= -17
x= 47 y= -114 z= -16
x= 48 y= -111 z= -18
x= 45 y= -112 z= -12
x= 46 y= -113 z= -16
x= 43 y= -110 z= -14
x= 46 y= -112 z= -17
x= 46 y= -117 z= -20
x= 45 y= -117 z= -18
x= 47 y= -113 z= -14
x= 45 y= -111 z= -15
x= 45 y= -112 z= -20
x= 43 y= -115 z= -20

According to the data sheet the zero rotation output should be 40 max. on each axis.

What are the supply voltages to the chip? Show a schematic of your circuit.

Sorry!

The supply voltage is 3,3 V
