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.

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.
