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 http://www.analog.com/media/en/technical-documentation/data-sheets/ADAU1761.pdf pages 7, 8 and 9.

 

I take a value from table 2

ie

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.

ie

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?
