The DAC8820ICDBG4 is a multiplying Digital-to-analog Converter (DAC) designed to operate from a single 2.7 to 5.5V supply. The applied external reference input voltage VREF determines the full-scale output current. An internal feedback resistor (RFB) provides temperature tracking for the full-scale output when combined with an external, current-to-voltage (I/V) precision amplifier. A parallel interface offers high-speed communications.
