I would like to know which description is correct?
Data sheet RevA Page 10 say "Gain pin connect to VDD".
But UG-459 Rev0 Page 6 Figure 5 described Gain pin pull up to Vref.
The Gain pin is a logic input pin. So depending on it being high or low the part will be configured with a 0 to Vref or 0 to 2xVref Span. On the Figure 5 schematic you refer to, LK4 shows the option of connecting to GND or VLogic. It is not configured to be pulled up to Vref.
