Load DAC A input and DAC registers with new data.
Contents of DAC B input registers are transferred to the
DAC register. Both outputs are updated.
Load DAC B input and DAC registers with new data.
Contents of DAC A input registers are transferred to the
DAC register. Both outputs are updated simultaneously.
Load DAC A input register with new data. DAC outputs
remain unchanged.
Load DAC B input register with new data. DAC outputs
remain unchanged.
Data in all input registers is transferred to respective DAC
registers. All DAC outputs are updated simultaneously.
New data is loaded into DAC A input register.
Data in all input registers is transferred to respective DAC
registers. All DAC outputs are updated simultaneously.
New data is loaded into DAC B input register.
Load all DACs with new data and update all DAC outputs
simultaneously. Both input and DAC registers are updated
with new data.
Load all input registers with new data. DAC outputs
remain unchanged.
Update all DAC outputs simultaneously. Device ignores
D11–D8. Do not send the data byte.
Extended command mode. The next word writes to the
power-down registers (see the Extended Command Mode
section).
Read DAC A data. The device expects an S
followed by an address word with R/W = 1.
Read DAC B data. The device expects an S
followed by an address word with R/W = 1.
