Re: I have a doubt. The ADC is the galileo 7298 (http://www.analog.com/static/imported-files/data_sheets/AD7298.pdf) which is 12bits. Why must read the Arduino interface is performed in 10 bits?

Hi MarisaCavalcante,

The Intel Galileo have 12 bit resolution to enable it in the Arduino IDE you need to use the command analogWriteResolution(12); to enable the 2 additional bits. The Intel Galileo Gen 2 Board have a 10 bit resolution ADC.
