LTC6655 Output Gain Stage


I plan to use the LTC6655 as a voltage reference for a DAC. On page 21 for the EVAL-AD5791SDZ User Guide, I see the LTC6655 being used with a non inverting op amp stage afterwards with a gain of 2. I was curious why the input into the op amp had 2 10k resistors in parallel? See the yellow highlight in the photo below.

Thank you!
