Note 2. All voltages with respect to ground
Note 3. AVSS, DVSS and HVSS must be connected to the same analog ground plane.
Note 4. MIN, RIN, LIN, MICIN, AINR1, AINL1 pins
Max is smaller value between (AVDD+0.3)V and 4.0V.
Note 5. PDN, CSN, CCLK, CDTI, LRCK, MCLK, BICK, SDTI pins
Max is smaller value between (TVDD+0.3)V and 4.0V.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Note 2. All voltages with respect to ground
Note 6. If each power supply is gradually switched on or off, some supply current may occur at the other power supply
that is still switched on during the supply voltage transition time.
