Note 1. All voltage with respect to ground.
Note 2. AVSS, DVSS, MVSS and SVSS must be connected to the same analog ground plane.
Note 3. LIN1, RIN1, LIN2, RIN2, BEEP1, BEEP2 and MIN pins
Note 4. EXTL, EXTR, INTL, INTR, PRENL and PRENR pins
Note 5. MCLK, LRCK, BICK, SDTI, PDN, CSN, CCLK, CDTI and MUTE pins
Note 6. Wiring density is 50% or more.
Note 7. Headphone-Amp and Speaker-Amp shouldn’t be powered up at the same time. The maximum
power supply voltage of SVDD is 3.3V.
Note 8. Headphone-Amp and Speaker-Amp can be powered up at the same time.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Note 1. All voltage with respect to ground.
Note 9. Minimum value is higher value between 2.6V and “AVDD – 0.1”V.
Note 10. When Ta (max) is 85°C, SVDD (max) is 3.3V. Then Headphone-Amp and Speaker-Amp shouldn’t be powered
up at the same time.
When Ta (max) is 70°C, SVDD (max) is 3.6V. Then Headphone-Amp and Speaker-Amp can be powered-up at
the same time.
