Guaranteed by characterization, not production tested.

Guaranteed by design, not production tested.

ADCVDD and DVDD can be powered from an internal LDO or, alternatively, can be powered from external 1.8 V rail, which may result in a lower power solution.

Pace is a digital function and incurs no power penalty.
