Note 2. All voltages with respect to ground.
Note 3. VSS1, VSS2, and VSS3 must be connected to the same analog plane.
Note 4. LIN1/IN1-, RIN1/IN1+, LIN2/IN2-, RIN2/IN2+, LIN3/IN3-, RIN3/IN3+ and SPIN pins
The maximum value is low value either (AVDD+0.3)V or 6.0V.
Note 5. RVINP and RVINN pins
The maximum value is low value either (SVDD+0.3)V or 6.0V.
Note 6. SDA, SCL and PDN pins.
The maximum value is low value either (TVDD+0.3)V or 6.0V.
Pull-up resistors at SCL and SDA pins should be connected to (TVDD + 0.3)V or less voltage.
Note 7. In case that PCB wiring density is 300% or more. This power is the AK4213 internal dissipation that does not
include power of externally connected headphone and speaker.
Note 8. In the case of Ta=85ºC, HP-Amp and SPK-Amp must not be powered-up simultaneously. When SPK-Amp be
used, HP-Amp should power-down, and the power of SPK-Amp should less than 1.3W @8Ω.
Note 9. In the case of Ta=70ºC, HP-Amp and SPK-Amp can be powered-up simultaneously. When HP-Amp and
SPK-Amp be used simultaneously, the power of HP-Amp should less than 30mW @16Ω, and the power of
SPK-Amp should less than 1.2W @8Ω.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
