    Hi Hiroyuki-san, 

    Both your schematic and I2C sequence looks correct to me. You are sending the correct data to update the DAC output, and it looks like the DAC is acknowledging the I2C commands. 

    Do you have a load on the output? Had you previously set a power down command to the device? The default power mode is on in low power mode. 

    Can you try an I2C read command to check if the data was stored correctly?

    Best,
