DAC2932 SBAS279C − AUGUST 2003 − REVISED OCTOBER 2004 Dual, 12ĆBit, 40MSPS DigitalĆtoĆAnalog Converter FEATURES D Dual, 12-Bit, 40MSPS Current Output DAC D Four 12-Bit Voltage Output DACs—for Transmit www.DataSheet4U.com Control DESCRIPTION The DAC2932 is a dual 12-bit, current-output digital-to-analog converter (DAC) designed to combine the features of high dynamic range and very low power consumption. The DAC2932 converter supports update rates of up to 40MSPS. In addition, the DAC2932 features four 12-bit voltage output DACs, which can be used to perform system control functions. The advanced segmentation architecture of the DAC2932 is optimized to provide a high spurious-free dynamic range (SFDR). The DAC2932 has a high impedance (> 200kΩ) differential current output with a nominal range of 2mA and a compliance voltage of up to 0.8V. The differential outputs allow for either a differential or single-ended analog signal interface. The close matching of the current outputs ensures superior dynamic performance in the differential configuration, which can be implemented with a transformer. Using a small geometry CMOS process, the monolithic DAC2932 is designed to operate within a single-supply range of 2.7V to 3.3V. Low power consumption makes it ideal for portable and battery-operated systems. Further optimization by lowering the output current can be realized with the adjustable full-scale option. The full-scale output current can be adjusted over a span of 0.5mA to 2mA. ...
