No. Pin Name  I/O  Function 
31 PDN  I 
Power-Down Mode Pin 
When “L”, the AK4589 is powered-down, all digital output pins go “L”, all registers 
are reset. When CAD1/0 pins are changed, the AK4589 should be reset by PDN pin. 
32 MASTER  I 
Master Mode Select Pin 
“H”: Master mode, “L”: Slave mode 
DZF2 O 
Zero Input Detect 2 Pin            (Table 13) 
When the input data of the group 1 follow total 8192 LRCK cycles with “0” input 
data, this pin goes to “H”. And when RSTN bit is “0”, PWDAN bit is “0”, this pin 
goes to “H”. It always is in “L” when P/S pin is “H”. 
33 
OVF O 
Analog Input Overflow Detect Pin 
This pin goes to “H” if the analog input of Lch or Rch overflows. 
34 DZF1  O 
Zero Input Detect 1 Pin          (Table 13) 
When the input data of the group 1 follow total 8192 LRCK cycles with “0” input 
data, this pin goes to “H”. And when RSTN bit is “0”, PWDAN bit is “0”, this pin 
goes to “H”. Output is selected by setting DZFE pin when P/S pin is “H”. 
35  LOUT4-  O  DAC4 Lch Negative Analog Output Pin 
36  LOUT4+  O  DAC4 Lch Positive Analog Output Pin 
470pF capacitor should be connected 
between LOUT4- and LOUT4+. 
37  ROUT4-  O  DAC4 Rch Negative Analog Output Pin 
38  ROUT4+  O  DAC4 Rch Positive Analog Output Pin 
470pF capacitor should be connected 
between ROUT4- and ROUT4+. 
39  LOUT3-  O  DAC3 Lch Negative Analog Output Pin 
40  LOUT3+  O  DAC3 Lch Positive Analog Output Pin 
470pF capacitor should be connected 
between LOUT3- and LOUT3+. 
41  ROUT3-  O  DAC3 Rch Negative Analog Output Pin 
42  ROUT3+  O  DAC3 Rch Positive Analog Output Pin 
470pF capacitor should be connected 
between ROUT3- and ROUT3+. 
43  LOUT2-  O  DAC2 Lch Negative Analog Output Pin 
44  LOUT2+  O  DAC2 Lch Positive Analog Output Pin 
470pF capacitor should be connected 
between LOUT2- and LOUT2+. 
45  ROUT2-  O  DAC2 Rch Negative Analog Output Pin 
46  ROUT2+  O  DAC2 Rch Positive Analog Output Pin 
470pF capacitor should be connected 
between ROUT2- and ROUT2+. 
47  LOUT1-  O  DAC1 Lch Negative Analog Output Pin 
48  LOUT1+  O  DAC1 Lch Positive Analog Output Pin 
470pF capacitor should be connected 
between LOUT1- and LOUT1+. 
49  ROUT1-  O  DAC1 Rch Negative Analog Output Pin 
50  ROUT1+  O  DAC1 Rch Positive Analog Output Pin 
470pF capacitor should be connected 
between ROUT1- and ROUT1+. 
51  LIN  I  Lch Analog Input Pin 
52  RIN  I  Rch Analog Input Pin 
53 VCOM  - 
Common Voltage Output Pin 
2.2µF capacitor should be connected to AVSS externally. 
54 VREFH  - 
Positive Voltage Reference Input Pin, AVDD
