TIMING AND DATA FORMAT
MS6323
16-Bits Stereo Audio DAC
The MS6323 accepts input serial data formats of 16-bit word length. Left and right data words are time
multiplexed. The MSB must always be first. The format of data input is shown in Figs. 2 and 3. With a HIGH level on
the word select input (WS), data is placed in the left input register and with LOW level on the WS input, data is placed
in the right register (Fig. 1). The data in the input registers are simultaneously latched in the output registers which
control the bit switches. Internal bias currents I
BL
and I
BR
are each added to the full scale output current I
FS
in order to
achieve the maximum dynamic range at the outputs of OP1 and OP2(Fig. 1). In this way the maximum dynamic range
is achieved over the entire power supply range.
