  • DAC39J82: Multiple DAC39J82 sharing the power rails

    Resolved
    Part Number: DAC39J82 Other Parts Discussed in Thread: AFE7444 Hi, There are three DACs used in our design. All three operate at different sampling and update rate. Will there be any impact on performance if the power rails are shared? Example: Powering…

  • DAC39J82: Initialize multiple DAC39J82 NCMO's to the same relative phase

    TI Thinks Resolved
    Part Number: DAC39J82 I sort of understand the answer to time syncing several DAC39J82 together, which I will incorporate. I'm using the NCO and need to ensure each NCO in multiple chips come up at the same phase relative to each other. The syncing ensures…
