Digital input
Power down. Powers down all DACs overriding their individual power down settings
and all output stages. This pin is active low.
NLDAC
Digital input
Load DAC. Digital input active low. NLDAC must be taken low to update the DAC
latch from the holding latches.

ABSOLUTE MAXIMUM RATINGS
Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at or
beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical
Characteristics at the test conditions specified
ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically susceptible to
damage from excessive static voltages. Proper ESD precautions must be taken during handling and storage of this
device.
