摘要
在普物电学实验中可引入数字电表实验.本文介绍了双斜式模数转换电路的基本工作原理和7107单片模数转换器出脚功能、外围元件作用及参量选择原则,并给出了7107单片模数转换器在电测技术、非电量数字仪表设计和传感器设计中的具体应用.
Experiment on the principle and application of digital multimeter has been introduced into the colledge experimental physics course. Basic principles of dual-slope A/D converting circuits, functions of the pins and periphery of 7107 single chip A/D converter, tips on the selection of parameters, applications of 7107 single chip A/D converter in sensor design and the electric measurement of electric and non-electric quantities, have been explained.
