摘要
基于AD7705的万能信号输入电路的设计,电路采用16位的Σ-Δ型AD7705作为模数转换器,实现了电压、电阻、电流等不同量程信号输入,进而进行数据的存储和显示.本电路是智能显示仪表重要的一个环节.
The paper introduces the design of universal input circuit based on AD7705. Taking 16 bit -- AD7705 as the ADC, the circuit can accept, storage and display different input signal with different range, such as voltage, resistance and current. The circuit is also one of the most important parts of intelligent display instruments.
