PIN/FUNCTION
I/O
Function
I SDTO Source Select Pin
(Note 1)
“L”: Internal ADC output, “H”: DAUX input
SDOS pin should be set to “L” when TDM= “1”.
I Control Mode Select Pin
“L”: 3-wire Serial, “H”: I2C Bus
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.
I Audio Serial Data Clock Pin
I Input Channel Clock Pin
I DAC1 Audio Serial Data Input Pin
I DAC2 Audio Serial Data Input Pin
I DAC3 Audio Serial Data Input Pin
O Audio Serial Data Output Pin
I AUX Audio Serial Data Input Pin
I Double Speed Sampling Mode Pin (Note 1)
“L”: Normal Speed, “H”: Double Speed
I DAC4 Audio Serial Data Input Pin
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)
- Output Buffer Power Supply Pin, 2.7V5.5V
- Digital Power Supply Pin, 4.5V5.5V
- Digital Ground Pin, 0V
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.
I Test Pin
This pin should be connected to DVSS.
I Chip Address 1 Pin
I Chip Address 0 Pin
O DAC4 Lch Analog Output Pin
O DAC4 Rch Analog Output Pin
