What is ratiometric error?
Ratiometric Error is defined as the difference between the ratio that 0g offset or sensitivity changed and the ratio that Vdd changed, expressed as a percentage. For our specifications, ratiometric error is typically calculated for a +/- 5% change in Vdd from nominal. For example, the offset ratiometric error at Vdd = 3.3V +/- 5% is defined as the maximum absolute value of: Similarly, the sensitivity ratiometric error at Vdd = 3.
