这是我用过的非常好的A/D转换器，希望大家下来看看，在你的产品中使用高性能的芯片-This is what I used very good A / D converters, hope to see you down. you use the products of high-performance chip

由c51编程实现12位串行A/D转换器TLC2543采集11个通道模拟输入数据。单片机通过编程产生串行时钟，并按时序发送与接收数据位，完成通道方式/通道数据的写入和转换结果的读出。-C51 programming from the 12-bit serial A/D converter TLC2543 11-channel analog input collected data. Microcontroller programmed to generate the serial clock, a
