The AD5424/AD5433/AD5445 are CMOS 8-, 10-, and 12-bitcurrent 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 andmany other applications. These DACs utilize data readback,allowing the user to read the contents of the DAC register viathe DB pins. On power-up, the internal register and latches arefilled 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 thefull-scale output current. An integrated feedback resistor (RFB)provides temperature tracking and full-scale voltage outputwhen 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 alatched 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 availablein a small, 20-lead LFCSP and a small, 20-lead TSSOP.The EVAL-AD5445SDZ evaluation board is available forevaluating DAC performance. For more information, see theUG-333 evaluation board user guide.
