Hi Lutz, I'm still looking into what this could be caused by. Just to confirm - which SDOx is the customer using? Are the outputs coming out on the same SDOx or separate SDOA and SDOB? Regards,

Hi Cynthia, You were correct about the reference noise. Adding a larger capacitor in the place of C21 did not work, and just caused the reference to oscillate. So I tombstoned a resistor and large...
