Digital Ground Pin

Digital Power Supply Pin, 3.3V or 5.0V

Master Clock Input Pin

Power-Down Mode Pin

When at “L”,the Ak4393 is in power-down mode and

is held in reset.

The AK4393 should always be reset upon power-

up.

Audio Serial Data Clock Pin

The clock of 64fs or more than is recommended to

be input on this pin.

Audio Serial Data Input Pin

2’s complement MSB-first data is input on this pin.

L/R Clock Pin

Soft Mute Pin

When this pin goes “H”, soft mute cycle is initiated.

When returning “L”,the output mute releases.

Chip Select Pin in serial mode
