AFE4403: Power Consumption

Big Bill
Expert 1980 points
Part Number: AFE4403

Dear  All:

      I use the  AFE4403 to design measure SPO2, I care the power consumption because of  battery supply. But i don‘t find the AFE4403 power consumption in normal work.   can you supply the detailed parameter

include the quiescent dissipation? Thanks

    Hi,

    The power consumption of AFE4403 totally depends on the timing signals set using register. For example if your PRF is low, AFE spends more time in DYNAMIC power down phase as compared to the case with higher PRF. Thus lowering the current consumption.
    For the current numbers for each of the phase, please refer to "Electrical Characteristics (p.g no. 9,10)" of the datasheet.

    Regards,
