The DAC7821IPW is a CMOS 12-bit current output Digital-to-analog Converter (DAC) operates from a single 2.5 to 5.5V power supply, making it suitable for battery-powered and many other applications. This DAC operates with a fast parallel interface. Data read-back allows the user to read the contents of the DAC register via the DB pins. On power-up, the internal register and latches are filled with zeroes and the DAC outputs are at zero scale. The DAC7821 offers excellent 4-quadrant multiplication characteristics with a large signal multiplying bandwidth of 10MHz. 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.
