Questions for a fool
I wanted to just reach out to the analogue devices community for a bit of assistance. Im working with a AD5761 DAC and I am trying to give it appropriate bipolar voltages. Looking over the data sheet I see that I can use the ADP5070 in conjunction with a few other ICs to produce a bipolar voltage of -11v and +11v. The real question is do I really need +21v and -13v if I plan to only use +-10v? Its my first year in college and im not exactly a pro with PCB design so I also had some questions on the total power consumption as it wasn't entirely clear in the datasheet when I reviewed it. I have about 20 of my AD5761s I need to power and im not sure how many ADP5070s I might need which Is why I am asking for their total power consumption.
Anything helps, even insults on my intellect as I plan to be a good electrical engineer someday.
