只要把两个 DAC 交错接入一个单元,你就可以有效地使一个 DAC 的采样速率增加一倍。轮流更新每个 DAC,并切换到合适的输出端,就可以使整个系统的有效吞吐率加倍。在复用这些 DAC 的输出时使用高质量的高速开关,这对系统总体性能是至关重要的。本设计实例中的电流型 DAC 考虑到输出开关的电流 By interleaving two DACs into a single cell, you can effectively double the sampling rate of one DAC. Rotating each DAC in turn and switching to the right output doubles the effective throughput of the entire system. The use of high-quality high-speed switches in multiplexing the outputs of these DACs is crucial to the overall system performance. The current DAC in this design example takes into account the current of the output switch
