DESCRIPTIONThe DAC2932 is a dual 12-bit, current-outputdigital-to-analog converter (DAC) designed to combine the
features of high dynamic range and very low powerconsumption. The DAC2932 converter supports update
rates of up to 40MSPS. In addition, the DAC2932 featuresfour 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) differentialcurrent output with a nominal range of 2mA and acompliance voltage of up to 0.8V. The differential outputs
allow for either a differential or single-ended analog signalinterface. The close matching of the current outputs
ensures superior dynamic performance in the differentialconfiguration, which can be implemented with a
transformer. Using a small geometry CMOS process, themonolithic DAC2932 is designed to operate within a
single-supply range of 2.7V to 3.3V. Low powerconsumption makes it ideal for portable and
battery-operated systems. Further optimization bylowering the output current can be realized with theadjustable full-scale option. The full-scale output current
can be adjusted over a span of 0.5mA to 2mA.
For noncontinuous operation of the DAC2932, a full
power-down mode can reduce the power dissipation to aslittle as 25μW.
The DAC2932 is designed to operate with a single paralleldata port. While it alternates the loading of the input data
into separate input latches for both current output DACs(I-DACs), the updating of the analog output signal occurs
simultaneously. The DAC2932 integrates a temperaturecompensated 1.22V bandgap reference. The DAC2932also allows for additional flexibility of using an external ref-
erence.
The DAC2932 is available in a TQFP-48 package.
