(2) Output signal updating timing
The L.OUT and R.OUT signals are updated after the input of 3.5 clocks following the change point indicating
the end of the LRCK pin R-ch data input period. Therefore, when the clock is supplied to CLK only during
D/A conversion, the clock must be stopped after the L.OUT and R.OUT signals corresponding to the last input
data are output. Be aware that the L.OUT and R.OUT signals corresponding to the last sample data are not output,
especially when the clock is supplied to CLK only during a sample data period.

(3) Countermeasures against shock noise
It is recommended that a mute circuit be connected to the next stage of the D/A converter. If a mute circuit is
not provided, shock noise may occur when power is applied.
