I want to use this DAC in my new design. I have already on board two analog power rails: +7V and -4.5 V. In the data sheet minimum recommended Vcc voltage is +9V. But, I don't want to introduce new positive rail +9 V. Could I connect DAC's Vcc power to +7 V rail and negative Vss pin to -4.5V rail?
From DAC I need output voltage +-2.5V with current no more then +-1 mA per output.
Thank you in advance.
