AD9744ARU

Product Summary

The AD9744ARU is a high performance, low power CMOS digital-to-analog converter (DAC). The AD9744ARU is specifically optimized for the transmit signal path of communication systems. All of the devices share the same interface options, small outline package, and pinout, providing an up-ward or downward component selection path based on performance, resolution, and cost. The AD9744ARU offers exceptional ac and dc performance while supporting update rates up to 210 MSPS. The applications of the AD9744ARU include Wideband communication transmit channel, Direct IFs, Base stations, Wireless local loops, Digital radio links, Direct digital synthesis (DDS), Instrumentation.
