Hi Erin, DAC was connected to 3.3V power, so full range would be from 0 to 3.3V with input code from 0x0000 to 0x3FFF At the beginning this was the case, next day I realize that DAC output is different: Code 0x0000 > DAC output =midscale Code 0x3FFF > DAC output =midscale Code 0x2000 > DAC output =0V Code 0x1FFF > DAC output =3.3V Alexei
