AD5544ARS

四，电流输出，串行输入16位/ 14位DAC Quad, Current-Output, Serial-Input 16-/14-Bit DACs

Product Details

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.
