Note 5. All voltages with respect to ground. VSS1 and VSS2 must be the same voltage.
Note 6. INP/AIN, INN pins
Note 7. IRSTN, I2CSEL, EXTEEP, SI/EEST, SDA/SO, SCL/SCLK, JX1, JX0, SDIN1, LRCK, and BICK pins
Note 8.Pull-up resistors at SDA and SCL pins must be connected to the DVDD voltage or less.
Do not turn off the power supplies when the SDA and SCL pins are pulled-up to DVDD.

Note 5. All voltages with respect to ground. VSS1 and VSS2 must be the same voltage.
Note 9. The power-up sequence between AVDD, DVDD and DVDD18 is not critical. But all power supplies must be
ON before starting operation of the AK7756.
