GENERAL DESCRIPTION
The AD5543/AD5553 are precision 16-/14-bit, low power,
current output, small form factor digital-to-analog converters
(DACs). They are designed to operate from a single 5 V supply
with a ±10 V multiplying reference.
The applied external reference, V
REF
, determines the full-scale
output current. An internal feedback resistor (R
FB
) 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 ×
4.7 mm) 8-lead MSOP and 8-lead SOIC packages.

All static performance tests (except I
OUT
) 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 +IN op amp is grounded, and the DAC I
OUT
is tied to the −IN op amp. Typical values represent average readings measured at 25°C.
2
These parameters are guaranteed by design and are not subject to production testing.
3
All ac characteristic tests are performed in a closed-loop system using an
AD8038
I-to-V converter amplifier except for THD where an
AD8065
was used.
4
All input control signals are specified with t
R
= t
F
= 2.5 ns (10% to 90% of 3 V) and timed from a voltage level of 1.5 V.

ABSOLUTE MAXIMUM RATINGS
Table 2.
AD5543/AD5553
Stresses above those listed under Absolute Maximum Ratings
may cause permanent 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
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
