摘要
为了实现测控系统中采样数据的模数转换,采用了一种单通道低功率高速CMOS 8位A/D转换器ADC081S051,给出了该A/D转换器的主要特点,工作原理,使用ADC081S051设计的采样放大电路,同时给出了ADC081S051与51单片机的接口电路及驱动程序。
In order to realize the analog-digital conversion of sample data in measurement and control system, an 8 bit A/D converter is introduced, which using single-channel and low power COMS. The main features and work principle of the A/D converter is proposed, and the sampling amplifying circuit designed with ADC081S051 is given, at the same time the interface and drivers for MCS-51 single chip computer are also provided.
