DAC0–7
Input registers to DAC registers
indicated by ones, DAC outputs
updated, equivalent to software
LDAC. (No effect on DACs
indicated by zeros.) DAC7–
DAC4 are only valid on the
MAX1021. These bits are don’t-
care bits for the MAX1043.

Power-Up
Power up individual DAC buffers indicated by data
in DAC0 through DAC3. A one indicates the DAC
output is connected and active. A zero does not
affect the DAC’s present state.
