The AD5544 is packaged in the compact 28-lead SSOP and 32-  
lead LFCSP. The AD5554 is packed in the compact 28-lead SSOP.  
GENERAL DESCRIPTION  
The AD5544/AD5554 quad, 16-/14-bit, current output, digital-  
to-analog converters (DACs) are designed to operate from a  
2.7 V to 5.5 V supply range.  
The EV-AD5544/45SDZ is available for evaluating DAC perfor-  
mance. For more information, see the UG-285 evaluation board  
user guide.  
The applied external reference input voltage (VREFx) determines  
the full-scale output current. Integrated feedback resistors (RFB)  
provide temperature-tracking, full-scale voltage outputs when  
combined with an external I-to-V precision amplifier.

A double-buffered serial data interface offers high speed, 3-wire,  
SPI- and microcontroller-compatible inputs using serial data in  
CS  
(SDI), a chip select ( ), and clock (CLK) signals. In addition,  
a serial data out pin (SDO) allows for daisy-chaining when multiple  
packages are used. A common, level-sensitive, load DAC strobe  
LDAC  
(
) input allows the simultaneous update of all DAC outputs  
from previously loaded input registers. Additionally, an internal  
power-on reset forces the output voltage to 0 at system turn-on.
