GENERAL DESCRIPTION
The AD5543/AD5553 are precision 16-/14-bit, low power,
current output, small form factor digital-to-analog converters.
They are designed to operate from a single 5 V supply with a
±10 V multiplying reference.
The applied external reference V
output current. An internal feedback resistor (R
R-2R and temperature tracking for voltage conversion when
combined with an external op amp.
A serial-data interface offers high speed, 3-wire microcontroller
compatible inputs using serial data in (SDI), clock (CLK), and
chip select (CS).
The AD5543/AD5553 are packaged in ultracompact
(3 mm 4.7 mm) MSOP-8 and SOIC-8 packages.

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.
