Hello Neeraj, Thank you for your reply. I understood there is no power up sequence. Could you check your idea as below by the EVM of yours? ------------------------------------------------------------------------------------------------------ >Can you ask the customer to power the DVDD to 3.3V and Gnd(0V) the AVDD at the very beginning. Apply the clock signal and send mid >code to the DAC wait for 5 clock cycles and apply 3.3V to AVDD and DAC should output 0V. ----------------------------------------------------------------------------------------------------- It may take your time, but check it please. Best Regards, Naoki Aoyama
