One Channel 0-10V DAC I2C Communication

Hi , I’m trying to interfacing a NCD DAC 0-10V to a adafruit feather board. Is there a reason why the scanner is returning back an address of 0x01. Also my ncd Dac is always outputting a voltage of 3.3V. I have a MCP4725 breakout board that works as it should as test device. Both the ncd DAC and 4-20mA transmitters are returning address values of 0x01. When I scan known devices with same code addresses returned are as expected.


Can you provide a photo of how you have everything connected?
