      I'm trying to use an ADC sigma delta which converts an analog signal with amplitude between 0-5 Volts. I don't understand how to set the ADC reference : in fact when I select the input range VSS-VDDA the reference automatically is set to 1.25 V , that is not the right value for me because in this way i would convert a signal with an amplitude greater than the reference. How can i do?Can someone  help me?
