The AD5424 / AD5433 / AD5445 are CMOS 8-, 10-, and 12-bit current output digital-to-analog converters (DACs), respectively. These devices operate from a 2.5 V to 5.5 V power supply, making them suitable for battery-powered applications and many other applications. These DACs utilize data readback, allowing 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 0s and the DAC outputs are at zero scale. As a result of manufacturing with a CMOS submicron process, they offer 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) provides temperature tracking and full-scale voltage output when combined with an external I-to-V precision amplifier. While these devices are upgrades of the AD5424 / AD5433 / AD5445 in multiplying bandwidth performance, they have a latched interface and cannot be used in transparent mode. The AD5424 is available in a small, 20-lead LFCSP and a small, 16-lead TSSOP, while the AD5433 and AD5445 DACs are available in a small, 20-lead LFCSP and a small, 20-lead TSSOP. The EVAL-AD5445SDZ evaluation board is available for evaluating DAC performance. For more information, see the UG-333 evaluation board user guide.
