7407大电流供应，最大能有30ma，可以驱动电压高达30V，是理想的常用驱动芯片

以ADC0809和8051为核心，该系统有三个部分：数据采集，数据处理和显示，终端接收。具体包括控制、显示、A/D转换器、电平转换接口、个人计算机等。设计中用ADC0809进行8路数据的采样，利用MCS-51单片机的串行口发送和接收数据。显示部分由8155、75452、7407和LED数码显示器构成。硬件设计应用电子设计自动化工具，软件设计采用模块化编程方法。

基于单片机的多路数据采集系统的设计方案，采用的是AD0809和51单片机，及LED液晶显示-To ADC0809 and 8051 as the core of the system, including three parts: data collection, data processing and display, the terminal receiver. Including its control, display, A/D converter, power conversion i
