GENERAL DESCRIPTION
The AD5544/AD5554 quad, 16-/14-bit, current-output, digitalto-analog converters are designed to operate from a single 5 V supply.
The applied external reference input voltage (VREF) 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.
