Hi Vichu,
Welcome to TI's e2e Community.
There are no internal calibration registers in the ADC128S102, I do not think the EVM is calibrated.
The output codes in decimal are converted to voltage with the following formula:
Vin = (ADC Code/4096)*VA. The EVM board sets VA=3.3V by default, You can use an external reference or supply from 2.7V to 5.25V as well.
