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 VREF determines the full-scale
output current. An internal feedback resistor (RFB) facilitates the
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 ϫ 4.7 mm) MSOP-8 and SOIC-8 packages.

NOTES
1All static performance tests (except IOUT) are performed in a closed-loop system using an external precision OP177 I-to-V converter amplifier. The AD5543 R FB terminal
is tied to the amplifier output. The op amp +IN is grounded and the DAC I OUT is tied to the op amp IN. Typical values represent average readings measured at 25 °C.
2These parameters are guaranteed by design and are not subject to production testing.
3All ac characteristic tests are performed in a closed-loop system using an AD841 I-to-V converter amplifier.
4All input control signals are specified with tR = tF = 2.5 ns (10% to 90% of 3 V) and timed from a voltage level of 1.5 V.

*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.
