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.
