Thanks for sharing a schematic! May I ask how the inductive load is related to this circuit? Is this load something connected to the ADC inputs, or is it some other circuit within the system? Looking at the schematic, I noticed the L1 (10uH) inductor on AVDD. This inductor may be interacting with the bypass capacitors and creating an LC resonator. I would recommend removing this inductor since it could be leading to ringing on the AVDD supply.
