Product Number: AD5675R
Laterly I was working a circuit containing the 8-channel DAC AD5675R. I was able to write to and read back the DAC value. However, the DAC remains zero, when I can read back the set value from the DAC register.
I have checked the hardware routes. And it seems to me that the configuration pins are properly routed. The schematic is attached as follows.
A strange thing is that the reference output of the AD5675R remains zero after power up. I think the reference output should be 2.5 V after power up. Dose it imply that the IC is damaged? Could anyone give me some hint on this problem? Thanks!
