The AD54051 is a dual CMOS, 12-bit, current output digitalto-analog converter (DAC).This device operates from a 2.5 V to 5.5 V power supply, making it suited to battery-powered and other applications. The applied external reference input voltage (VREF) determines the full-scale output current. An integrated feedback resistor (RFB) provides temperature tracking and full-scale voltage output when combined with an external I-to-V precision amplifier. This device also contains all the 4-quadrant resistors necessary for bipolar operation and other configuration modes. This DAC utilizes data readback, allowing the user to read the contents of the DAC register via the DB pins.
