Principle and Application of 16-Bits DAC of MAX5631 with 32 Channels

In this paper MAX5631,a 16-Bits DAC with 32 channels is introduced,its construction and princiˉple are discussed in detail.At the same time,three working modes and timing of MAX5631are introduced.At last,an example of serial interface between MAX5631 and AT89C51 and programs are given.
