Preliminary Product Specification
There is a digital fine gain implemented for each ADC to adjust the fine gain errors between the ADCs. The gain is
controlled by fgain_branch* as defined in table 22. There will be no missing codes when using digital fine gain, due to
higher resolution internally.
To enable the fine gain function the register bit fine_gain_en has to be activated, set to '1'.
