PIC ADC V-REF Switching

[urakhai911]

Hey World,

I am writing a program where I am sampling from a temperature sensor and a light sensor in succession. Both the sensors require different v-ref inputs.

gnd - 1.5 and 1.5 - 3.3

If I were to change the reference voltage which the ADC uses in my code after each conversion, would it affect the accuracy of my conversion?

yes, if your code doesn't factor that in.

no, if your code does factor that in.
