I´m desinging a dual analog output with 2 AD5422 IC´s. Can i join the pin 2 (DVCC) of the 2 AD5422, for suppling external electronic?
Yes, connecting both DVCC pins together in this manner is fine.
As you know, DVCC is a digital supply pin (DVCC SELECT pin connected to GND), but can also be configured as a 4.5V LDO output (DVCC SELECT pin left unconnected).
In terms of shorting the DVCC pin on two AD5422 IC's, what could be done would be as follows:
I have DVCC SELECT pin of AD5422 IC #1 and IC#2 unconnected. So, my question is if i can join both DVCC pins together, with your internal LDO enabled.
Your option above, i understand it´s correct (IC #1 supply DVCC of IC#2).
Thank you so much Tracey,
