Hello, Offset and gain errors are commonly calibrated out in software by applying a standard y=m*x+b fit to the measured curve vs. the desired ideal transfer function. For more information on ADC errors and calibration please take a look at the TI Precision Labs videos below. Video 3.2 specifically covers this topic. The transfer function of the ADC from output code to input voltage is explained in the Figure below.
