14-Bit High Bandwidth Multiplying DAC With Serial Interface

The AD5444 AD5446 are CMOS 12-bit and 14-bit, current output, digital-to-analog converters (DACs). Operating from a single 2.5 V to 5.5 V power supply, these devices are suited for battery-powered and other applications.
As a result of the CMOS submicron manufacturing process, these parts offer excellent 4-quadrant multiplication characteristics of up to 12 MHz.
These DACs use a double-buffered, 3-wire serial Interface that is compatible with SPI, QSPI, MICROWIRE, and most DSP Interface standards. On power-up, the internal Shift register and Latches are filled with 0s, and the DAC output is at zero scale.
The applied external reference input voltage (VREF) determines the full-scale output current. These parts CAN handle 10 V inputs on the reference, despite operating from a single-supply power supply of 2.5 V to 5.5 V. An integrated feedback resistor (RFB) provides temperature tracking and full-scale voltage output when combined with an external current-to-voltage Precision Amplifier The AD5444 AD5446 DACs are available in small 10-lead MSOP packages, which are pin-compatible with the AD5425 AD5426 AD5432 AD5443 family of DACs
