Note 2. All voltages with respect to ground.
Note 3. VSS1 and VSS2 must be connected to the same analog ground plane.
Note 4. LIN1/IN−, RIN1/IN+, LIN2 and RIN2 pins. Max is smaller value between (AVDD+0.3)V and 4.6V.
Note 5. SDA/CDTI, SCL/CCLK, CAD0/CSN, SDATA, LRCK, BICK, MCKI, PDN and I2C pins. Max is smaller value
between (DVDD+0.3)V and 4.6V.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Note 6. When AVDD and DVDD are supplied separately, AVDD should be powered-up after DVDD rises up to 1.6V or
more. When the AK4370 is powered-down, DVDD should be powered-down at the same time or later than
AVDD. When AVDD and HVDD are supplied separately, AVDD should be powered-up at the same time or
earlier than HVDD. When the AK4370 is powered-down, AVDD should be powered-down at the same time or
later than HVDD.
Note 7. Max is smaller value between (AVDD+0.2)V and 3.6V.
