Hi Machida-san, Thanks for sharing. Talking to the team, there is likely no intentional path between AGND and DGND, so it is difficult to measure. There may be some unintentional parasitic path through which AGND and DGND is connected inside the device, but there is no spec for this and as it could be unintentional, there may be variations between devices. We recommend customers connect the two GNDs on their PCB so they are referenced to the the same ground close to the device. Best regards, Samiha
