Note 2. All voltages with respect to ground.
Note 7. The power up sequence between AVDD, DVDD and SVDD is not critical. It is not permit to power DVDD off
only when AVDD or SVDD is powered up. When the power supplies except DVDD are partially powered OFF,
the AK4633 must be reset by bringing PDN pin “L” after these power supplies are powered ON again. If AVDD is
powered off when DVDD is powered up, the PMADC bit should be set to “0” before AVDD is powered off.
