DESCRIPTION
AVDD, HPVDD, DBVDD = 1.8V, AGND = 0V, DCVDD = 1.5V, DGND = 0V, T
XTI/MCLK = 256fs (12.288MHz).
All figures are quiescent, with no signal.
All figures are measured with the audio interface in master mode (MS = 1).
The power dissipation in the headphone itself is not included in the above table.
