hi All,

I was looking at the datasheet of Allegro Hall-effect sensor ACS711ELCTR-25AB-T. It says there accuracy is based on 3.3v and they have this note as well
Customers that plan to operate the device from a 5 V regulated
supply should contact their local Allegro sales representative regarding expected device accuracy levels under these bias conditions.
What does this mean ? should the IC be powered by 3.3v to get the desired accuracy ? Or as they say, get in touch with there product manager about it ?

It seems to say that pretty clearly, yes.
