Tool/software:
Applied to the unipolar output scene with output analog 0~5V, the schematic diagram is drawn in a bipolar way, and we want to change to unipolar. REFNF (5), REFNS(6) For these two feet I reserved two short ground zero ohm resistance, such as, this is my understanding of unipolar connection. The other is to connect 1 or 2 points to AGND on the basis of bipolar power supply circuit. Please also consult the original unipolar working mode connection, thank you
