Hi Marvin,

1. Who is customer ? or did you performing any testing with DAC11001B EVM.

2. This circuit used select reference "REFGND" either buffered or direct short with AGND.

J30, 1-2 - REFGND short with AGND

J30,2-3 - REFGND buffered version of AGND.

Typically buffered version help to isolate AGND from REFGND which helps to provide clean reference to DAC.
