Note 3. All voltages with respect to ground.
Note 4. AVSS and HVSS must be connected to the same analog ground plane.
Note 5. I2C, RIN4/IN4−, LIN4/IN4+, MIN/LIN3, RIN3, RIN2/IN2−, LIN2/IN2+, LIN1/IN1−, RIN1/IN1+ pins
Note 6. PDN, CSN/CAD0, CCLK/SCL, CDTI/SDA, SDTI, LRCK, BICK, MCKI pins
Pull-up resistors at SDA and SCL pins should be connected to (TVDD+0.3)V or less voltage.
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.
Note 7. The power-up sequence between AVDD, DVDD, TVDD and HVDD is not critical. When AVDD, HVDD or
TVDD is powered OFF, the power supply current of DVDD at power-down mode may be increased. When
AVDD, HVDD or DVDD is powered OFF, the power supply current of TVDD at power-down mode may be
increased. DVDD and TVDD should not be powered OFF while AVDD or HVDD is powered ON.
