Part Number: DAC53701

Hi Team,

Customer would like to design DAC53701.

Is DAC53701 able to output 1.1V w/o I2C control at the beginning?
Would you please help review  and provide your comments?

if DAC53701 is not able to do this, do you have othe recommendation?

Thanks for help!

    Hi SHH,

    Yes. The DAC53701 has programable non-volatile memory that can be configured to output 1.1V on start up. This configuration needs to be programmed once by setting the DAC-DATA register to output 1.1V, powering up the output in the GENERAL-COFG register, setting any other required registers (based on what features they might be using), and then setting the NVM-PROG bit to '1' in the TRIGGER register.

    On the next power up the output will go to 1.1V without the need for I2C control. 

    Best,
