NOTE: Electrical tests are performed at wafer probe to the limits shown. Due to variations in assembly methods and normal yield loss, yield after packaging is not
guaranteed for standard product dice. Consult factory to negotiate specifications based on dice lot qualifications through sample lot assembly and testing.

ELECTROSTATIC
DISCHARGE SENSITIVITY
Any integrated circuit can be damaged by ESD. Burr-Brown
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 degrada-
tion 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
published specifications.
Digital Inputs: All digital inputs of the DAC8043 incorpo-
rate on-chip ESD protection circuitry. This protection is
designed and has been tested to withstand five 2500V
positive and negative discharges (100pF in series with 1500Ω)
applied to each digital input.
Analog Pins: Each analog pin has been tested to Burr-
Brown’s analog ESD test consisting of five 1000V positive
and negative discharges (100pF in series with 1500Ω) ap-
plied to each pin. V
REF
and R
FB
show some sensitivity.

CAUTION: 1. Do not apply voltages higher than V
DD
or less than GND
potential on any terminal except V
REF
(Pin 1) and R
FB
(Pin 2). 2. The digital
control inputs are ESD protected: however, permanent damage may occur on
unprotected units from high-energy electrostatic fields. Keep units in conduc-
tive foam at all times until ready to use. 3. Use proper anti-static handling
procedures. 4. Absolute Maximum Ratings apply to both packaged devices.
Stresses above those listed under Absolute Maximum Ratings may cause
permanent damage to the device.
