Analog Gain in the ADC 

 

The only analog Gain available in the  is located at the sensor level, in the ADC 
converter.  
This “Preamp Gain” is in fact a variation of the ramp of the comparator of the ADC.  
Then 3 Values are available : x1, x2 and x4. A gain x1 in a 12 bits conversion is equivalent 
to x4 in 10 bits.
