Note 2. All voltages with respect to ground. VSS1 and VSS2 must be connected to the same analog
ground plane.
Note 3. The maximum Digital input voltage is smaller value between (LVDD+0.3)V and 4.3V.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Note 4. The power up sequence between AVDD and TVDD is not critical.
Note 5. The VREFL pin must be connected to VSS2.
Note 6. Do not turn off the power supply of the AK4438 with the power supply of the peripheral device
turned on. When using the I2C interface, pull-up resistors of SDA and SCL pins should be
connected to TVDD or less voltage.
