AD5544ARSZ

AD5544 is a quad, 16-bit, current output, digital to-analog converter (DAC). It is designed to operate from a 2.7V to 5.5V 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. It is widely used in application such as automatic test equipment, instrumentation, digitally controlled calibration etc.
