ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

Not Internally Connected.
The selected DAC register becomes transparent
when LDAC is LOW. It is in the latched state
when LDAC is HIGH.
Asynchronous Reset Input. Sets all DAC
registers to either zero-scale (000
H
) or mid-
scale (800
H
) when LOW. RESETSEL determines
which code is active.
When LOW, a LOW on RESET will cause all
DAC registers to be set to code 000
H
. When
RESETSEL is HIGH, a LOW on RESET will set
the registers to code 800
