PACKAGE
44L MQFP
CLR
(Active Low) Analog Clear. Sets the output
voltages to RGND. (Each RGND is common to a
DAC pair.)
CLR
does not reset the digital latches.
When
CLR
is brought back high, the DAC outputs
revert back to their original outputs as determined
by the data in their DAC latches.
When this logic input is taken low, the contents of
the input latches are transferred to their respective
DAC latches. (Active Low) Data is latched on
rising edge.
Addresses DAC0 to DAC7 for loading the eight
input latches.
