Note 2. All voltages with respect to ground.
Note 3. I2CA, RIN4/IN4−, LIN4/IN4+, MIN/LIN3, RIN3, RIN2/IN2−, LIN2/IN2+, LIN1/IN1−, RIN1/IN1+ pins
Note 4 PDN, CADA, SCLA, SDAA pins
Pull-up resistors at SDAA and SCLA pins should be connected to (TVDD1+0.3) V or less voltage.
Note 5. SDTI, LRCK, BICK, MCKI pins
Note 6 XP, XN, YP, YN, CADT, SCLT, SDAT pins
Pull-up resistors at SDAT and SCLT pins should be connected to (TSVDD+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.

Note 2. All voltages with respect to ground.
Note 7. The power-up sequence among AVDD, DVDD, TVDD1, TVDD2, HVDD and TSVDD is not critical. The PDN
pin should be held to “L” when power-up. The PDN pin should be set to “H” after all power supplies are
powered-up. The AK4673 should be operated by the recommended power-up/down sequence shown in “System
Design (Grounding and Power Supply Decoupling)” to avoid pop noise at line output and headphone output.
When one of power supplies is partially powered OFF, the power supply current at power-down mode may be
increased. All the power supplies should be powered OFF when the power supply is powered OFF.
* AKEMD assumes no responsibility for the usage beyond the conditions in this datasheet.
* SDAA and SDAT are written as SDA, and also SCLA and SCLT are written as SCL unless otherwise
specified in this datasheet.
