Table 3. DAC Selection
The CODEn command (B[23:20] = 0000) updates the
CODE register contents for the selected DAC(s). Changes
to the CODE register content based on this command will
not affect DAC outputs directly unless the LDAC is in a
low state or the DAC latch has been configured to be
transparent. Issuing the CODEn command with DAC
SELECTION = ALL DACs is equivalent to CODE_ALL
(B[23:16] = 10000000). See
The LOADn command (B[23:20] = 0001) updates the
DAC register content for the selected DAC(s) by upload-
ing the current contents of the CODE register. The
LOADn command can be used with DAC SELECTION =
ALL DACs to issue a software load for all DACs, which
is equivalent to the LOAD_ALL (B[23:16] = 10000001)
command. See
The CODEn_LOAD_ALL command (B[23:20] = 0010)
updates the CODE register contents for the selected
DAC(s) as well as the DAC register content of all DACs.
Channels for which the CODE register content has not
been modified since the last load to DAC register or
LDAC operation will not be updated to reduce digital
crosstalk. Issuing this command with DAC_ADDRESS =
ALL is equivalent to the CODE_ALL_LOAD_ALL (B[23:16]
= 1000001x) command. The CODEn_LOAD_ALL com-
mand by definition will modify at least one CODE reg-

SELECTION = ALL DACs or use the LOAD_ALL com-
mand. See
The CODEn_LOADn command (B[23:20] = 0011) updates
the CODE register contents for the selected DAC(s) as
well as the DAC register content of the selected DAC(s).
Channels for which the CODE register content has not
been modified since the last load to DAC register or

command. See
The CODE_ALL command (B[23:16] = 10000000)
updates the CODE register contents for all DACs. See
Table
The LOAD_ALL command (B[23:16] = 10000001) updates
the DAC register content for all DACs by uploading the
current contents of the CODE registers. See
The CODE_ALL_LOAD_ALL command (B[23:16] =
1000001x) updates the CODE register contents for all
DACs as well as the DAC register content of all DACs.
