摘要
文中以8位的 DAC0832为例阐述用低位的 D/A 转换芯片获得高位的 D/A 分辨率的方法,并给出具体电路和芯片与8031的接口程序,最后提出提高转换精度的措施。
In this paper,a way that how to gain high resolution from little bit D/A chip is introduced.The circuit diagram is il- lustrated by DAC0832 as well as program.At last in the paper,some advice about how to improve precision of conversion are given.
