VDD Sensitivity of MMA8451Q

The MMA8451Q datasheet specifies a 'nominal' VDD supply voltage of 2.5V.

 

I wonder if anyone knows what effect a different supply voltage might have on this device? Would it have an effect on the offset? or on the sensitivity? Many other accelerometers specify these values.

Our application is battery powered, so the supply voltage, if unregulated, would drop steadily during the life of the product. Also, how sensitive is the MMA8451Q to noise on the VDD supply?

 

Thanks in advance!
