Note:
The three ground references AIGND, AOGND, and DGND should be
used discreetly each according to its designated purpose. Actually, we
offer the individual GND pin for AI, AO and DIO to provide best signal
quality. However, all the signals on the DA&C card need to refer to the
same GND finally. So we test and choice a best point to connect
AIGND, AOGND and DGND together. In short, this is base on the
"single-point" ground principle.
