利用TLC5620构成12位D/A和A/D电路

Appling TLC5620 to Constitute 12 Bit D / A and A / D

介绍利用8位4通道通用D/A芯片TLC5620构成12位高精度D/A和A/D电路的方法,该电路设计简单,具有A/D和D/A转换功能,可以在很多场合应用.给出了具体电路和软件的编制框图,分析了误差构成,并介绍了电路的调试方法.

This paper introduces how to use hig accuracy D/A and A/D. The circuit is 8 bit 4 channels D/A chip TLC5620 to realize 12 bit simple, and has the conversion function of A/D and D /A and can be used in many cases. The concrete circuit and software flow diagram are proposed and the composition of error and the method of debugging the program are also discussed.
