hi
m having a circuit which has sensor that gives output from 0-1.5 v ,i will be converting 0-1.5 v to 0-5 v using opamp which i will further give to adc and then to uc but the output isnt linear for a change of value=1 of physical property ..there is a voltage change of 1mV .but after reaching a level of 0.5 v the scale changes to 2:1 i.e, for a change of value=2 of physical property ..there is a voltage change of 1mV.what should i do?
with best regards
