POWER CONSUMPTION
(This table represents the power consumption for individual circuit blocks within the codec) (See (Note 15) )
15. Unless otherwise noted, test conditions are as follows: All zeros input, sample rate = 48 kHz; No load.
16. RESET# held HI, all HDA Bus clocks and data lines are running; HDA Interface running with support
for unsolicited responses; All converters are in D3 state.
17. Full-scale single-ended output signal into a 10 k
 load.
18. Full-scale differential output signal into a 10 k
 load.
(The following table demonstrates the total power consumption for typical system operation. These total codec
power numbers are derived from the individual block power consumption numbers in the previous table.)
