The AD5444/AD54461 are CMOS 12-bit and 14-bit, currentoutput, digital-to-analog converters (DACs). Operating from asingle 2.5 V to 5.5 V power supply, these devices are suited forbattery-powered and other applications.
As a result of the CMOS submicron manufacturing process,these parts offer excellent 4-quadrant multiplication characteristicsof up to 12 MHz.
These DACs use a double-buffered, 3-wire serial interface thatis compatible with SPI®, QSPI™, MICROWIRE™, and most DSPinterface standards. On power-up, the internal shift register andlatches are filled with 0s, and the DAC output is at zero scale.
The applied external reference input voltage (VREF) determinesthe full-scale output current. These parts can handle ±10 Vinputs on the reference, despite operating from a single-supplypower supply of 2.5 V to 5.5 V. An integrated feedback resistor(RFB) provides temperature tracking and full-scale voltage outputwhen combined with an external current-to-voltage precisionamplifier. The AD5444/AD5446 DACs are available in small10-lead MSOP packages, which are pin-compatible with theAD5425/AD5426/AD5432/AD5443 family of DACs.
The EV-AD5443/46/53SDZ board is available for evaluatingDAC performance. For more information, see the UG-327evaluation board user guide.
