Hello Guys I am using ADC10 on a F1232, A0 is wired to the adc out of a pressure sensor, the sensor is powered by the same battery as the MCU, in order to get the Vcc as a reference point, does REFOUT has to be set and it be powered by this reference output? Thanks Jay

ADC10 REFOUT on?

NO. As long as you have selected Vcc as the A/D reference, and have
decoupled all the pins as per the data sheets then NO. Equally important
is to have a dedicated AVcc supply. This can be as simple as a Vcc track
that ONLY connects to Analog devices, and which is separately decoupled.
