*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
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.

Clock Input. Positive-edge triggered, clocks
data into shift register.
Serial Register Input. Data loads directly
into the shift register MSB first. Extra leading
bits are ignored.
Internal Matching Feedback Resistor. Con-
nects to external op amp for voltage output.
DAC Reference Input Pin. Establishes DAC
full-scale voltage. Constant input resistance
versus code.
DAC Current Output. Connects to inverting
terminal of external precision I-to-V op amp
for voltage output.
Analog and Digital Ground
Positive Power Supply Input. Specified range
of operation 5 V ± 10%.
Chip Select. Active low digital input. Transfers
shift-register data to DAC register on rising
edge. See Truth Table for operation.

*The AD5543 contains 1040 transistors. The die size measures 55 mil ϫ 73 mil, 4,015 sq. mil.
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
AD5543/AD5553 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.
