AD1833A
DAC CONTROL REGISTER 2
DAC Control Register 2 contains individual channel mute
controls for each of the six DACs. Default operation (bit = 0) is
muting off. Bits 9 through 6 of Control Register 2 are reserved
and should be programmed to zero (see Table VIII).

DAC CONTROL REGISTER 3
Stereo Replicate
The AD1833A 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.
