nRF52833 SAADC Power Consumption Specification

rmarchand

Hello,

I'm starting to investigate using the nRF52833 as part of my design and i wanted to clarify the specification in the datasheet.  it states the following:

Does this specification include only the power consumption of the SAADC or also the power consumption of DMA (or core?).  what does the 1.37mA include in this specification?  Also, what is the nominal input voltage that this is measured against?

    This is the average current of both the SAADC and DMA controller. The SAADC has peak current of ~700µA during acquisition and conversion. 

    Also, what is the nominal input voltage that this is measured against?

     3V supplied to VDD. See Current consumption.
