EVAL-AD5662/AD5660/AD5640/AD5620

Hi everyone!

 

I'm using EVAL-AD5662/AD5660/AD5640/AD5620 and have AD5660 as my DAC and I noticed that there are grounding problems to the AGND and DGND pins of the evaluation board. It is said in the datasheet of the evaluation board that the analog GND and DGND are connected at a location close to the AD56xx but I am measuring around a 650kohms resistance between the two grounds.  Please be so kind to provide a copy of the circuit layout of the evaluation board (gerber file and/or board (brd) file). I would just like to see if the grounding, AGND and DGND really do have a connection.

Thank you very much.
