AD5696RARUZ Gain connection

Question

On page 8 of the AD5696RARUZ datasheet, it says that the DAC's gain = 2 when the GAIN pin is connected to VLogic. On page 16, under Transfer Function, it says Vdd instead. Which is it? Maybe it doesn't matter?

Hi W9IP , 
 The GAIN pin should be connected to VLOGIC, the digital power supply, to ensure proper operation and avoid incorrect or unstable output voltage. This is because the GAIN pin is a digital input pin that follows logic input and output specs like the VINL and VINH, which are all referenced to VLOGIC.
