Readback function The AD54051 is a CMOS, 12-bit, dual-channel, current output
digital-to-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.
As a result of manufacturing with a CMOS submicron process the
device offers excellent 4-quadrant multiplication characteristics,
with large signal multiplying bandwidths of up to 10 MHz.
The applied external reference input voltage (VREF) determines
the full-scale output current. An integrated feedback resistor (RFB) …
