1 Guaranteed by characterization, not production tested.

2 Guaranteed by design, not production tested.

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

4 Pace is a digital function and incurs no power penalty.
