No. Pin Name I/O Function
31 PDN I Power-Down Mode Pin
When “L”, the AK4588 is powered-down, all output pin goes “L”, all registers are
reset. When CAD1/0 pins are changed, the AK4588 should be reset by PDN pin.
32 MASTER I Master Mode Select Pin
“H”: Master mode, “L”: Slave mode
DZF2 O
ZeroInputDetect2Pin (Note1)
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 is “H”.
33
OVF O
Analog Input Overflow Detect Pin (Note 2)
This pin goes to “H” if the analog input of Lch or Rch overflows.
34 DZF1 O
ZeroInputDetect1Pin (Note1)
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 is “H”.
35 LOUT4 O DAC4 Lch Analog Output Pin
36 NC - No Connect
No internal bonding.
37 ROUT4 O DAC4 Rch Analog Output Pin
38 NC - No Connect
No internal bonding.
39 LOUT3 O DAC3 Lch Analog Output Pin
40 NC - No Connect
No internal bonding.
41 ROUT3 O DAC3 Rch Analog Output Pin
42 NC - No Connect
No internal bonding.
43 LOUT2 O DAC2 Lch Analog Output Pin
44 NC - No Connect
No internal bonding.
45 ROUT2 O DAC2 Rch Analog Output Pin
46 NC - No Connect
No internal bonding.
47 LOUT1 O DAC1 Lch Analog Output Pin
48 NC - No Connect
No internal bonding.
49 ROUT1 O DAC1 Rch Analog Output Pin
50 NC - No Connect
No internal bonding.
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 PVSS externally.
54 VREFH - Positive Voltage Reference Input Pin, AVDD
Notes:
1. The group 1 and 2 can be selected by DZFM2-0 bits.
2. This pin becomes OVFE bit if OVFE bit is set to 1.
