描述 Description

The DAC7822 is a dual, CMOS, 12-bit, current output digital-to-analog converter (DAC). This device operates from a 2.5V to 5.5V power supply, making it suitable for battery-powered and many other applications.The DAC7822 operates with a fast parallel interface. Data readback 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 DAC7822 offers excellent 4-quadrant multiplication characteristics, with 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. The DAC7822 also includes the resistors necessary for 4-quadrant multiplication and other configuration modes. The DAC7822 is available in a 40-lead QFN package.
