Hi,
With typically 0.6V and 0.8V as feedback for the power circuits, what will be the recommendation of reference, supply voltages to source[margin up to -10%] or sink[margin up to +10%]?
Thanks a lot

Hi,
I didn't understand your question. Can you please explain ? Are you looking for reference and power supply margin recommendations?

Yes, right. Also, want to know how do reference voltage and output voltage affect resolution?
Thank you
Rudra
Hi,
What is the variation in output voltage you are looking for? For max voltage of 0.8V from DAC, I suggest go with 1.8V reference with VDD = 3.3V
resolution is fixed 1-0 bit for DAC53608, if you are using 1.8V reference, one code change corresponds to 1.76mV. If you need more finer adjustments, you need to choose 12bit DAC. Note that 1.8V is the minimum reference input voltage for DACx3608.
Hope this clarifies.

Hi,
Thank you so much for your kind help.
Variation in output voltage is 0.6V to 0.8V.
Thanks & Regards
