AD1833
DAC CONTROL REGISTER II
DAC Control Register II contains individual channel mute
controls for each of the 6 DACs. Default operation (bit = 0) is
muting off. Bits 9 through 6 of Control Register II are reserved
and should be programmed to zero, see Table VIII.

Stereo Replicate
The AD1833 allows the stereo information on Channel 1
(SDIN1—Left 1 and Right 1) to be copied to Channels 2 and 3
(Left/Right 2 and Left/Right 3). These signals can be used in an
external summing amplifier to increase potential signal SNR.
Stereo Replicate mode can be enabled by writing to Control
Bit 5, see Table XI. Note that replication is not reflected in
the zero flag status.
