ASAHI KASEI [AK4589]
MS0339-E-00 2004/09
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
2.2
µ
F capacitor should be connected to AVSS externally.
54 VREFH - Positive Voltage Reference Input Pin, AVDD
