Note 8. BICKB, SYNCB, SDTIB pins
WARNING: Operation at or beyond these limits may result in permanent damage to the device.

Note 2. All voltages with respect to ground.
Note 9. The power-up sequence between AVDD, PVDD, SAVDD, DVDD, TVDD2 and TVDD3 is not critical.
The PDN pin should be held to “L” when power-up. The PDN pin should be set to “H” after all power supplies are
powered-up. The AK4671 should be operated by the recommended power-up/down sequence shown in “System
Design (Grounding and Power Supply Decoupling)” to avoid pop noise at receiver output, headphone output and
line output.
When the power is OFF partially except for DVDD, all power management bits (PMVCM, PMMP, PMMICL,
PMMICR, PMADL, PMADR, PMDAL, PMDAR, PMPLL, PMLOOPL, PMLOOPR, PMAINL1, PMAINR1,
PMAINL2, PMAINR2, PMAINL3, PMAINR3, PMAINL4, PMAINR4, PMLO1, PMRO1, PMLO2, PMRO2,
PMLO2S, PMRO2S, PMLO3, PMRO3, PMSRA, PMSRB, PMPCM, PMSAD) should be “0” or the PDN pin
should be “L”. DVDD should not be powered OFF while AVDD, PVDD, SAVDD, TVDD2 or TVDD3 is
powered ON. When only DVDD is OFF, the current of 10mA to 100mA around may occur.
