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.
