Dear Team, 

In my design I am using DAC80502, Where VDD is 5V and VrefIO is 3.3V. What is the minimum and maximum voltage at VoutA and VoutB?

    Hi Hridya, 

    Maximum output is 3.3V with REF-DIV and BUF-GAIN set to 1. REF-DIV set to 0 and BUF-GAIN set to 1 is invalid for this reference and VDD configuration. Minimum output is 0V, but keep in mind the zero-code error and footroom requirements when sinking current (we require 300mV worst case at 10mA). 

    Best,
