This may have already been answered in a previous post (https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/963866/dac80501-possible-output-voltage-with-3-3v-power-supply)
I'd like to confirm that the output range with a 3.3V supply, internal reference, BUFF-GAIN = 1 and REF-DIV =0 would be linear as if the max code was for 5V output, but would clip at about 3.1V i,e, 1 LSB would be 1.2207mV.
Thank you
