The AD54151 is a CMOS 12-bit, dual-channel, current output digital-to-analog converter. This device operates from a 2.5 V to 5.5 V power supply, making it suited to batter y-powered applications as well as many 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 current-to-voltage precision amplifier. In addition, this device contains all the 4-quadrant resistors necessar y for bipolar operation and other configuration modes.
