GENERAL DESCRIPTION

The AD5544/AD5554 quad, 16-/14-bit, current-output, digital-

to-analog converters are designed to operate from a single 5 V

supply.

The applied external reference input voltage (V_REF) determines

the full-scale output current. Integrated feedback resistors (R_FB

provide temperature-tracking, full-scale voltage outputs when

combined with an external I-to-V precision ampliﬁer.

A doubled-buffered serial-data interface offers high-speed,

3-wire, SPI- and microcontroller-compatible inputs using

serial-data-in (SDI), clock (CLK), and a chip-select (CS). 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 simultaneous update of

all DAC outputs from previously loaded input registers. Addi-

tionally, an internal power ON reset forces the output voltage to

zero at system turn ON. An MSB pin allows system reset asser-

tion (RS) to force all registers to zero code when MSB = 0, or

to half-scale code when MSB = 1.
