摘要
本文从工程应用的角度提出了两种有效的D/A转换器复用方法,并详述了其工作原理,电路特性和应用领域.特别是其中的硬件顺序刷新方法在应用于数目较大的多通道D/A 转换时可以大幅度降低电路成本,具有显著的应用价值.
This paper offers two effective methods ofD/A multiplex at an angle of applications,ofwhich the principls,circuit specialities andapplication fields are described in detail.Especially,the method called the hardwarerefreshing in sequence can reduce thecircuit corts to a great extent and haveoutline practical value when it is used for anumerous multichannel D/A conversion situation.
