Product Summary

The AD9751AST is a High-Speed TxDAC+ D/A Converter. It integrates a high-quality 10-bit TxDAC+ core, a voltage reference, and digital interface circuitry into a small 48-lead LQFP package. The AD9751AST offers exceptional ac and dc performance while supporting update rates up to 300 MSPS. The device has been optimized for ultrahigh-speed applications up to 300 MSPS where data rates exceed those possible on a single data interface port DAC. The applications of the AD9751AST include: Communications: LMDS, LMCS, MMDS, Base Stations, Digital Synthesis, QAM and OFDM.
