Note 3. All indicated voltages are with respect to ground VSS1, VSS2, VSS3 and VSS4 must be connected to the analog
ground plane.
Note 4. Analog input pins are AINL and AINR.
Note 5. Digital input pins are TSTI, SDA, SCL and XTI.
WARNING: Operating at or beyond these limits may result in permanent damage to the device. Normal operation is not
guaranteed at these critical conditions.

Note 6. AVDD and DVDD must be the same voltage. The power up sequence between AVDD and DVDD is not critical
but the PDN pin must be “L” until all power supplies are ON, then put the PDN pin to “H”. All power supplies
of the AK7600 are must be ON. Do not turn any power supply off (means the same voltage as ground or
floating) independently. When using the AK7600 with I²C bus, the power supply of the AK7600 must not be
turned off unless the power supplies of the surrounding device are turned off.
