Maxim最新推出MAX19692 12位、2．3Gsps数/模转换器(DAC),该款DAC能够在多个奈奎斯特频带直接合成高频、宽带信号,为高速DAC确立了新的工业标准。MAX19692能够在直流至高于2GHz的频率范围内直接合成高达1GHz带宽的信号。器件提供出众的动态性能,输出频率为1200MHz(工作在第3奈奎斯特频带)时,无杂散动态范围(SFDR)为68dB,比同类产品在此输出频率下的SFDR高出14dB。 Maxim introduces the MAX19692 12-bit, 2.3Gsps digital-to-analog converter (DAC), which directly synthesizes high frequency and wideband signals in multiple Nyquist bands, setting a new industry standard for high speed DACs. The MAX19692 directly synthesizes signals up to 1GHz in the frequency range from dc up to 2GHz. The device offers superior dynamic performance with an unscented SFDR of 68dB at an output frequency of 1200MHz (operating in the 3rd Nyquist band), which is 14dB above the SFDR of its class at this output frequency.
