Function
1
SDOS
I
SDTO Source Select Pin
(Note 1)
“L”: Internal ADC output, “H”: DAUX input
SDOS pin should be set to “L” when TDM= “1”.
2
I2C
I
Control Mode Select Pin
“L”: 3-wire Serial, “H”: I
2C Bus
3
SMUTE
I
Soft Mute Pin
(Note 1)
When this pin goes to “H”, soft mute cycle is initialized.
When returning to “L”, the output mute releases.

“L”: Normal Speed, “H”: Double Speed
12
SDTI4
I
DAC4 Audio Serial Data Input Pin
13
DZFE
I
Zero Input Detect Enable Pin
“L”: mode 7 (disable) at parallel mode,
zero detect mode is selectable by DZFM3-0 bits at serial mode
“H”: mode 0 (DZF1 is AND of all eight channels)
14
TVDD
-
Output Buffer Power Supply Pin, 2.7V
∼5.5V
15
DVDD
-
Digital Power Supply Pin, 4.5V
∼5.5V
16
DVSS
-
Digital Ground Pin, 0V
17
PDN
I
Power-Down & Reset Pin
When “L”, the AK4529 is powered-down and the control registers are reset to default
state. If the state of P/S or CAD0-1 changes, then the AK4529 must be reset by PDN.
18
TST
