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 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
(SDI), a chip select (CS), 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.
The MSB pin allows system reset assertion (RS) to force all registers
to zero code when MSB = 0 or to half-scale code when MSB = 1.
The AD5544 is packaged in the compact 28-lead SSOP and 32-
lead LFCSP. The AD5554 is packed in the compact 28-lead SSOP.
The EV-AD5544/45SDZ is available for evaluating DAC perfor-
mance. For more information, see the UG-285 evaluation board
user guide.
