8/10/12位高帶寬乘法DAC并行接口ad5424/ad5433/ad5445數(shù)據(jù)表

　　The AD5424/AD5433/AD54451 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.
