PIN/FUNCTION
I/O Function
I Chip Address 0 Pin
I Chip Address 1 Pin
I Parallel/Serial Select Pin
“L”: Serial control mode, “H”: Parallel control mode
O ADC1 Audio Serial Data Output Pin
O ADC2 Audio Serial Data Output Pin
- Output Buffer Power Supply Pin, 2.7V∼5.5V
- Digital Power Supply Pin, 4.5V∼5.5V
- Digital Ground Pin, 0V
I TDM I/F Format Mode Pin in parallel control mode
“L”: Normal mode, “H”: TDM mode
I/O Control Data Input Pin in serial control mode
I2C pin= “L”: CDTI (3-wire Serial), I2C pin= “H”: SDA (I²C Bus)
I Audio Data Interface Format 1 Pin in parallel control mode
I Control Data Clock Pin in serial control mode
I2C pin= “L”: CCLK (3-wire Serial), I2C pin= “H”: SCL (I²C Bus)
I Audio Data Interface Format 0 Pin in parallel control mode
I Chip Select Pin in 3-wire serial control mode
This pin should be connected to DVDD at I²C bus control mode
I Power-Down & Reset Pin
When “L”, the AK4627 is powered-down and the control registers are reset to default
state. If the state of PS pin or CAD1-0 pins change, then the AK4627 must be reset by
the PDN pin.
