Note 10. The power up sequence among AVDD, TVDD, SVDD, and PVDD is not critical. The PDN pin must be held to
“L” when power-up. The PDN pin must be set to “H” after power supplies are powered-up. The AK4213 should
be operated by the recommended power-up/down sequence shown in “System Design” to avoid pop noise at
speaker output and headphone output.
The AK4213 supports the following two cases of partial power ON/OFF. In these cases, the
PDN pin must be “L”.
1. TVDD=SVDD=ON: AVDD=PVDD can be power ON/OFF.
2. TVDD=ON: AVDD=PVDD=SVDD can be power ON/OFF.
When the power state is changed from OFF to ON in the above cases, the PDN pin must be
changed from “L” to “H” after all power supply pins are supplied. “L” time of 150ns or more is
needed to reset the AK4213.
* AKEMD assumes no responsibility for the usage beyond the conditions in this datasheet.
