When I config the LTC2666-12, I use 0x00301000 to write code to DAC0 and update it. But there isn't any voltage output(the output is 0V). Then I use 0x00301100 to write another code to DAC0, but there isn't any voltage output(the output is 0V), and there isn't any output on SDO(it should be 00301000, but all is 0). I am so confused. What's wrong with my configuration?
