Table 1 Powerdown Mode Current Consumption Examples
Notes:
1. AVDD, HPVDD, DBVDD = 3.3V, AGND = 0V, DCVDD = 1.5V, DGND = 0V, TA = +25oC. Slave Mode, fs = 48kHz,
XTI/MCLK = 256fs (12.288MHz).
2. All figures are quiescent, with no signal.
3. The power dissipation in the headphone itself not included in the above table.
