I2C Compatibility
The MAX5813/MAX5814/MAX5815 are fully compatible
with existing I2C systems. SCL and SDA are high-imped-
ance inputs; SDA has an open drain which pulls the data
line low to transmit data or ACK pulses. Figure 8 shows a
typical I2C application.
I2C User-Command Register Map
This section lists the user accessible commands and
registers for the MAX5813/MAX5814/MAX5815.
Table 5 provides detailed information about the Command
Registers.
CODEn Command
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
LOADn Command
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)
CODEn_LOAD_ALL Command
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 command. The
CODEn_LOAD_ALL command by definition will modify at
least one CODE register. To avoid this, use the LOADn
command with DAC SELECTION = ALL DACs or use the
CODEn_LOADn Command
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
LDAC operation will not be updated to reduce digital
crosstalk. Issuing this command with DAC SELECTION
= ALL DACs is equivalent to the CODE_ALL_LOAD_ALL
CODE_ALL Command
The CODE_ALL command (B[23:16] = 10000000)
updates the CODE register contents for all DACs. See
LOAD_ALL Command
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 Table 5.
CODE_ALL_LOAD_ALL Command
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.
See Table 5.
