摘　　要：本文介绍一种由ＣＤ４０５１实现高三位Ａ／Ｄ转换，然后和８０９８片内１０位Ａ／Ｄ结果组合在一起，形成１３位Ａ／Ｄ转换的方法。此法不仅硬件电路简单，而且工作稳定可靠。The article introduces that the high three - bit A/D transformer is realized by CD4051, and then is combined with the result of ten-bit A/D transformation so as to form the thirteen-bit A/ D transformation. This method not only makes the hardware circuit simple, but also makes the state of operation stable and reliable.
