4. NOTES ON USE
(1) Input signal format
Input data must be input as 2’s complement, MSB first, and backward justification.
2’s complement is a method of expressing both positive numbers and negative numbers as binary numbers.
See the table below.

Make sure that the delimiter of each bit of the data (SI) and the changing timing of LRCK coincide with the
falling edge of CLK.
It is necessary that 16 clocks be input during 1 sample data period (16 bits). Make sure that the time width
of 1 bit coincides with one cycle of the clock.
In the input data, the 16 bits preceding the change point of LRCK (shown in “1 sample data period” in Fig.
4-1, and Fig. 4-2) are considered to be valid data and are incorporated for use in D/A conversion.
