- AVDD and DVDD remain at 3.3 V
- RESET remains pulled high from an always-on 1.8 V rail
- IOVDD drops to 0 V because the system 1.8 V rail is turned off during the ship mode
- No SPI communication is required

Hi,
No, we would not recommend operating the AD5940 with AVDD and DVDD powered while IOVDD is at 0 V.
This would be a partially powered device condition and would violate the device's operating requirements. In general, powering only some supply domains while leaving others unpowered can create unintended current paths through internal protection structures and digital circuitry.

Mark
