yes as i said my changing value is not large enough it is like only 2 volts variation a low angular speed (like my head moving) so i m losing 3volts

i ll try with the resistive divider but i heard it is very bad for the temperature drifting....??

and i have a reference voltage with my sensor (pin 3) it is like 2.4v very accurate do you think i can use that in a way as a vref+ and - (with diodes or something)


thank s anyways
