O DAC1 Rch Analog Output Pin
- No Connect
No internal bonding.
- No Connect
No internal bonding.
I Lch Analog Input Pin
I Rch Analog Input Pin
O Zero Input Detect 2 Pin
(Note 2)
When the input data of the group 1 follow total 8192 LRCK cycles with “0” input data,
this pin goes to “H”.
O Analog Input Overflow Detect Pin (Note 3)
This pin goes to “H” if the analog input of Lch or Rch is overflows.
O Common Voltage Output Pin, AVDD/2
Large external capacitor around 2.2µF is used to reduce power-supply noise.
I Positive Voltage Reference Input Pin, AVDD
- Analog Power Supply Pin, 4.5V∼5.5V
- Analog Ground Pin, 0V
O Zero Input Detect 1 Pin
(Note 2)
When the input data of the group 1 follow total 8192 LRCK cycles with “0” input data,
this pin goes to “H”.
I Master Clock Input Pin
I Parallel/Serial Select Pin
“L”: Serial control mode, “H”: Parallel control mode
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 Audio Data Interface Format 1 Pin in parallel control mode
I Control Data Clock Pin in serial control mode
I2C = “L”: CCLK (3-wire Serial), I2C = “H”: SCL (I2C Bus)
I Loopback Mode 0 Pin in parallel control mode
Enables digital loop-back from ADC to 4 DACs.
I/O Control Data Input Pin in serial control mode
I2C = “L”: CDTI (3-wire Serial), I2C = “H”: SDA (I2C Bus)
I TDM I/F Format Mode Pin (Note 1)
“L”: Normal format, “H”: TDM format
Notes: 1. SDOS, SMUTE, DFS, and TDM pins are ORed with register data if P/S = “L”.
2. The group 1 and 2 can be selected by DZFM3-0 bits if P/S = “L” and DZFE = “L”.
3. This pin becomes OVF pin if OVFE bit is set to “1” at serial control mode.
4. All input pins should not be left floating.
