Note 3. All voltages with respect to ground. VSS1 and VSS2 must be connected to analog ground.
Note 4. PMDAL/CAD0, PMDAR/CAD1, LOPS, CKS0/TDMI, CKS3, CKS2, CKS1, PMADL/SCL,
PMADR/SDA, SDTI, LRCK, BICK, MCKI, SDA, PS, LDOE and PDN pins. The external pull-up
resistors at the SDA and SCL pins should be connected to (TVDD+0.3) voltage or less.
Note 5. In case that PCB drawing density is more than 100%. The exposed pad on the bottom surface of
the package must be connected to VSS.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Note 3. All voltages with respect to ground. VSS1 and VSS2 must be connected to analog ground.
Note 6. When the LDOE pin = “L” VDD18 must be powered up either at the same time or after TVDD is
powered up. Internal LDO generates 1.8V, when the LDOE pin =“H”. The power-up sequence with
AVDD and TVDD is not critical. The PDN pin should be held “L” prior to when power is applied.
The PDN pin is allowed to be “H” after all power supplies are applied and settled. All power pins of
the AK4558 must be supplied. Do not turn any power supply off independently (neither grounded
nor floating). When using the AK4558 with I²C bus, the power supply of the AK4558 must not be
turned off unless the power supplies of the surrounding device are turned off.
*AKM assumes no responsibility for the usage beyond the conditions in this data sheet.
