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. 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 –0.1 –0.2 0 10,000 30,000 50,000 70,000 CODE 20,000 40,000 60,000 Figure 2.
