Note 5. All voltages with respect to ground.
Note 12. When the voltage of LVDD pin is low and a high level signal is output from LINEOUT, the output signal is
Note 13. The Minimum value is higher value between 2.6V and “AVDD – 0.1”V.
Note 14. The power up sequence among AVDD, LVDD, MVDD, DVDD, TVDD1, TVDD2, and SVDD is not critical.

When the power state is changed from OFF to ON in the above cases, the PDN pin should be
changed from “L” to “H” after all power supply pins (TVDD1, TVDD2, AVDD, DVDD, MVDD,
LVDD, and SVDD pins) are supplied. “L” time of 150ns or more is needed to reset the AK4691.
The AK4691 supports the following two cases of partial power ON/OFF. In these cases, the
PDN pin must be “L”.
clipped and the distortion of LINEOUT degrades. LVDD should be more than (0.6 x AVDD + 0.8)[V] at
LVOL2-0 bits = “000” and be more than (0.76 x AVDD + 0.8)[V] at LVOL2-0 bits = “001” and be more than
(1.19 x AVDD + 0.8)[V] at LVOL2-0 bits = “010” and be more than (1.36 x AVDD + 0.8)[V] at LVOL2-0 bits
= “100”in order to avoid clipping.
