摘要
介绍一种应用12位双D/A转换器TLC5618实现13位分辨率的D/A转换方法,给出了TLC5618与单片机AT89C55的接口电路及13位D/A转换的硬件实现原理,并给出了用C51编写的相应功能程序.此方法已应用于智能仪表和PLC模块的设计中.
A design method of 13 bit D/A converter resolution is introduced by using 12 bit dual D/A con- verter TLC5618. The hardware interface circuit between the TLC5618 and the microcontroller AT89C55 and the realization principle of hardware for 13 bit D/A converter resolution are presented, and the correla- tive function programs compiled with C51 are given. This method has a1ready been applied to the design of the smart instruments and PLC module.
