Quiz: How Well Do You Know Adaptive Power Switching?
Is your I/O module overheating? The AD74416H's Adaptive Power Switching (APS) can cut heat dissipation by up to 40% — but how well do you really understand how it works?

I only used the AD5755's A and B channels to output 24mA current, and the C and D channels were not used, what should I do with the pins REST_x, COMPDCDC_x, and IOUT_x/VOUT_x, and can I leave it floating or grounded？
Thanks for your answer！
Hi YolandaO .
For unused channels, the DAC output is disabled by default (DAC Control Register OUTEN=0). You can leave IOUTx and VOUTx floating. For RSETx, you can select the internal resistor (RSET=1) for the selected DAC channel. For COMPDCDCx, if you are using the internal compensation, it's ok to leave it open as well. But if you're using external resistor for compensation, a ~50 kΩ resistor in series with a 10 nF dc-to-dc compensation capacitor to ground is recommended.

Thank you very much for your guidance, and I would like to ask you to help me see if the schematic of the AD5755 is correct, as the size of the PCB is limited, so I want to minimize the layout area of the AD5755
