The accelerometer's data sheet is on the
US FIRST website here and is the best source of information on the device. Page 3 tells you that the power supply can range from 2.4V to 5.25V. The datasheet does list some example specs when you assume that the supply is 3V. If you look at the bottom of page 9, there is a section entitled
USING THE ADXL311 WITH OPERATING VOLTAGES OTHER THAN 3 V that should shed some light on the effects of a different supply voltage.
