DESCRIPTION solution fora wide variety of waveform-synthesisThe DAC2904isa monolithic, 14-bit, dual-channel, applications:high-speed Digital-to-Analog Converter (DAC), andis • Pin compatibility between family membersoptimizedto provide high dynamic performance while provides 10-bit (DAC2900), 12-bit (DAC2902),dissipating only 310mW. and 14-bit (DAC2904) resolution.
Operating with high update ratesof upto 125MSPS, • Pin compatibleto the AD9767 dual DAC.the DAC2904 offers exceptional dynamic • Gain matchingis typically 0.5%of full-scale, andperformance, and enables the generationof very-high offset matchingis specifiedat 0.02% max.output frequencies suitable for “Direct IF” • The DAC2904 utilizesan advanced CMOSapplications. The DAC2904 has been optimized for process; the segmented architecture minimizescommunications applicationsin which separateI and output-glitch energy, and maximizes the dynamicQ data are processed while maintaining tight-gain performance.and offset matching. • All digital inputs are +3.3V and +5V logicEach DAC hasa high-impedance differential-current compatible. The DAC2904 hasan internaloutput, suitable for single-ended or differential reference circuit, and allows useina multiplyinganalog-output configurations. configuration.
The DAC2904is availableina TQFP-48 package,
and is specified over the extended industrial
temperature rangeof –40°Cto +85°C.
