• Connecting Vref on AD5338R

    If I want to use an external reference with the AD5338R, how should I connect this to Vref?  If I tie Vref to the desired reference voltage (5V for example), will I kill the chip?

     

    My fear is that by connecting, a 5V rail straight to the Vref pin, this…

  • it seems there is a 660kHz noise present when output a 2.1~2.2V voltage

    I use a AD5338R to bias a power amplifier. There is two signal tone present around +/- 660kHz offset. I try sevral things to identify the source.

    1. if replace AD5338R by a LDO to bias PA , these two spur dissappeared;
    2. increase the AD5338R output to 2.3V…
