ADAU1761 Power Consumption

Question asked by pbthesp on Sep 16, 2015

I am trying to work out the power used by an ADAU1761.


Referring to the data sheet pages 7, 8 and 9.


I take a value from table 2


3v3, 48KHz SAI master = 1.51mA


Then add in values from table 3.

I am using the ADCs and DACs so I need a value for each.


3v3 Record, pll = 6.57mA

3v3 Playback to line, pll = 6.9mA


Giving a total so far of 14.98mA.


Does this include the core consumption?


What is table 4 used for, do I add these values to the above or are they to replace the values from table 3 when power management is used?
