ADC dynamic range : How can I  the maximum ADC conversion precision ?

Hi everyone,

I work with the stm32l073rz. I  measure the sensor with the ADC and the retrieved value is correct.

Now, I want to increase the precision. The sensor gives a little value (maximum 1.5V). Can I reduce the intern ADC voltage to increase the precision like this figure ?

Thank you very much for your help
