CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the DAC8043A features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

PIN FUNCTION DESCRIPTIONS
DAC Reference Input Pin. Establishes DAC full-
scale voltage. Constant input resistance versus
code.
Internal Matching Feedback Resistor. Connect
to external op amp output.
DAC Current Output, full-scale output 1 LSB
less than reference input voltage –V
Analog and Digital Ground.
Load Strobe, Level-Sensitive Digital Input.
Transfers shift-register data to DAC register
while active low. See truth table for operation.
12-Bit Serial Register Input, data loads directly
into the shift register MSB first. Extra leading
bits are ignored.
Clock Input, positive-edge clocks data into shift
register.
Positive Power Supply Input. Specified range of
operation 5 V ± 10%.
