Note 3. All voltages with respect to ground.
Note 4. AVSS, DVSS and HVSS must be connected to the same analog ground plane.
Note 5. I2C, 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 (DVDD+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.

Difference
Note 3. All voltages with respect to ground.
Note 7. The power-up sequence between AVDD, DVDD and HVDD is not critical. When only AVDD or HVDD is
powered OFF, the power supply current of DVDD at power-down mode may be increased. DVDD should not be
powered OFF while AVDD or HVDD is powered ON.
