GENERAL DESCRIPTION
The AD5544/AD5554 quad, 16-/14-bit, current output, digitalto-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.
