The AD5544 / AD5554 quad, 16-/14-bit, current output, digital-to-analog converters (DACs) are designed to operate from 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. An 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 packaged in the compact 28-lead SSOP

Product Detail
The AD5544 quad, 16-bit, current output, digital-to-analog converter (DAC) is designed to operate in a 2.7 V to 5.5 V supply range. But this voltage is limited up to 3.3 V due to EVAL-SDP-CB1Z restrictions.
The applied external reference input voltage (VREFx) determines the full-scale output current. Integrated feedback resistors (RFBx) 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), 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. An 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 a compact 28-lead SSOP. The EV-AD5544 board is used in conjunction with the EVAL-SDP-CB1Z system demonstration platform (SDP) board available from Analog Devices, Inc., which is purchased separately from the evaluation board. The USB-to-SPI communication to the AD5544 is completed using this Blackfin®-based demonstration board. The software offers a waveform generator.
