MAX5816 MAXIM [Maxim Integrated Products], MAX5816 Datasheet - Page 25

• Manufacturer Part Number: MAX5816
• Description: Ultra-Small, Quad-Channel, 12-Bit Buffered Output DAC with Internal Reference and I2C Interface
• Manufacturer: MAXIM [Maxim Integrated Products]

The CODEn_LOAD_ALL command 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 will not be updated to reduce digital crosstalk. 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. The
CODEn_LOAD_ALL command supports the multibyte protocol. See
Table 7. CODEnLOADALL (010) Command Format
Table 8. CODEnLOADn (011) Command Format
The CODEn_LOADn command 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 have not been modified since the last
load to DAC register will not be updated to reduce digital crosstalk. See
