8-Bit High Bandwidth Multiplying DACs With Serial Interface

The AD5450 is a CMOS 8-bit Current Output digital-to-analog converter. This device operates from a +2.5 V to 5.5 V power supply, making it suited to battery powered applications and many other applications.
This DAC utilizes 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 zeros and the DAC output is at zero scale. As a result of manufacture on a CMOS sub micron process, they offer excellent four quadrant multiplication characteristics, with large signal multiplying bandwidths of 10MHz.
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 Current to Voltage Precision Amplifier The AD5450 is available in small 8-lead TSOT & MSOP packages.
