Serial Data Output Pin
Data bits are presented MSB first, in 2 s complement format.
This pin is L in the power-down mode.
Left/Right Channel Select Pin
The fs clock is input to this pin.
Master Clock Input Pin
Serial Data Input Pin
Output data is clocked out on the falling edge of SCLK.
Power-Down Pin
When L , the circuit is in power-down mode.
The AK5353 should always be reset upon power-up.
