【Application】Design Application of CD4051 8-Channel Analog Multiplexer in Insulation Resistance Tester


In the application of the insulation resistance tester circuit design, Shanghai Guoxin's CD4051 is selected as the multiplexer for selecting the voltage level of the adjustment terminal. CD4051 is an 8-to-1 analog multiplexer with a supply voltage range of 5~15V. The analog switch has a wide digital control and analog signal transmission voltage range: digital signals with an amplitude of 4.5V to 18V can control analog signals with a peak-to-peak value of 18V. At the same time, the typical on-resistance is only 80 ohms, featuring low on-resistance and very low off-state leakage current.
