Description
I Rch Analog Input Pin
I Lch Analog Input Pin
O Voltage Reference Output Pin
Normally connected to AGND with a 0.1uF ceramic capacitor
in parallel with an electrolytic capacitor less than 4.7uF.
O Common Voltage Output Pin
Normally connected to AGND with a 0.1uF ceramic capacitor
in parallel with an electrolytic capacitor less than 4.7uF.
- Analog Ground Pin, 0V
- Analog Power Supply Pin, +2.7∼+5.5V
- Digital Power Supply Pin, +2.7∼+5.5V
- Digital Ground Pin, 0V
O Serial Data Output Pin
Data bits are presented MSB first, in 2 s complement format.
This pin is L in the power-down mode.
I Left/Right Channel Select Pin
The fs clock is input to this pin.
I Master Clock Input Pin
I Serial Data Input Pin
Output data is clocked out on the falling edge of SCLK.
I Power-Down Pin
When L , the circuit is in power-down mode.
The AK5353 should always be reset upon power-up.
I Serial Interface Format Pin
L : MSB justified, H : I²S
I Digital Input Level Select Pin
L : CMOS level (VA,VD=2.7∼5.5V), H : TTL level (VA,VD=4.5∼5.5V)
I Test Pin (Internal pull-down pin)
This pin should be left floating.
Note: All input pins except pull-down pins should not be left floating.
