ADXL345 / 350 offset problems

Hi, I have a question regarding ADXL350 operating voltage. It specifies 2.0 - 3.6V, the same as the ADXL345.


However, I have seen from operating the ADXL345 @ 3.3V that there is significant offset on the X / Y axes.


The ADXL345 document says this:



The ADXL345 is tested and specified at a supply voltage of

VS = 2.5 V; however, it can be powered with VS as high as 3.6 V

or as low as 2.0 V. Some performance parameters change as the

supply voltage changes: offset, sensitivity, noise, self-test, and

supply current.



So, can anyone tell me if I should use 2.5V ONLY to supply the ADXL350? Or, are voltages other than 2.5V going to cause offset on the ADXL350 as well?
